When plasma Ca concentration decreases... 1. Parathyroid hormone level increases 2. Parathyroid hormone level decreases 3. Ca and phosphate reabsorption increases 4. Ca and phosphate reabsorption decreases 5. Ca reabsorption decreases and phosphate reabsorption increases 6. Ca reabsorption increases and phosphate reabsorption decreases
Answer:
2. Parathyroid hormone level decreases
4. Ca and phosphate reabsorption decreases
Explanation:
When plasma Ca concentration decreases, the action of Parathyroid hormone level decreases which leads to Calcium and phosphate reabsorption decreases. Parathyroid hormone is responsible for the increase of calcium and phosphorus in the blood when there is low level in the blood so when the re is huge amount of calcium and phosphorus in the blood, the Parathyroid hormone activity decreases which decrease the reabsorption of calcium and phosphorus decreases.

What are australopiths, how many groups are there, and what do they date to? Which one is derived and therefore not part of our direct evolutionary line?
Answer and Explanation:
Australopithecines were a group of ancestral animals that were very similar to chimpanzees, but had common characteristics with humans, which is something normal, when we think that these animals are one of the ancestors of human beings. These animals walked on two legs, like humans, but they had very small brains and teeth that were bigger and heavier than those of humans. There were eight groups of australopithecines and they date from 8 million to 1.5 million years ago.
Among these groups, it is believed that Australopithecus afarensis is a group that has no direct ancestry with humans, being a group that did not thrive during the evolutionary process.
which gases does NOT contribute to greenhouse effect?
Answer:
Carbon monoxide is not a primary greenhouse gas. It contributes in a relatively small way directly to the greenhouse effect.Some of the typical properties of cancer cells are: (1) Self-sufficient growth and proliferation, (2) Defects in intracellular control mechanisms that normally arrest or permanently stop cell division in response to stress or DNA damage, (3) Ability to escape from home tissues (invasiveness) and to survive and proliferate in foreign sites (metastatic ability), and (4) Instability of the genome. True or False
Answer:
True
Explanation:
Cancer cells are abnormal cells that divide aggressively to form solid tumors, thereby differing from normal cells. Cancer cells do not need any stimulation to multiply them, i.e., they can synthesize their own growth factors that trigger uncontrolled cell proliferation. Mutations in genes associated with the progression through the cell cycle and programmed cell death (i.e., apoptosis) are a well-known hallmark of cancer cells. The mutated genes can be either 1-tumor suppressor genes that slow down cell division and repair DNA mistakes or 2-proto-oncogenes that normally help cells grow, and whose mutations cause normal cells to become cancerous (oncogenes are mutated forms of proto-oncogenes). Cancer cells are characterized by their invasiveness and metastatic potential, i.e., their ability to spread to healthy surrounding tissues through the lymph system and/or bloodstream, where these cells proliferate and produce new tumors. Finally, genomic instability, i.e., the increased susceptibility of cells to acquire and spread mutations at the genome level, is also a hallmark of cancer cells. Genomic instability results from damage to genes that regulate cell division and tumor suppressor genes.

Which of the following is the correct Lewis structure diagram for Sodium (Na)? (2 points)
Select one:
a. The letters Na with one dot
b. The letters Na with two dots
c. The letters Na with three dots
d. The letters Na with four dots
Answer:
a. The letters Na with one dot
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.
Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.
Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.
A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.
Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.
For example, the Lewis structure diagram for Sodium (Na) is •Na.
Answer:
Na with 1 dot

What are the jobs of rRNA, mRNA and tRNA?
What is the end product of the process?
Answer the question using complete sentences and the diagram.
Answer:
- I believe transcription.
- Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein development.
- the end product is RNA.

Use an examples to distinguish dominant and recessive phenotypes.
I'm a bit stuck and need some help. Much appreciated!
Think recessive phenotypes as paper and dominant phenotypes as teared paper. Once paper is teared, it can't be fixed. Not even tape. It'll just leave that mess exposed. Same with dominant phenotypes. It just takes one dominant trait to change the looks of future offspring.
If you don't tear the paper, everything is fine. Same with recessive phenotypes. As long as there's no contact with any dominant phenotypes, the looks of future offspring will change.

A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylthiocarbamide (autosomal dominant; common allele), but their mothers could not. Give the genotypes of the couple. If the genes assort independently and the couple has four children, what is the probability of all of them being brachydactylous
Answer:
The correct answer is -
A) BbTt x bbTt
B) .5^4 or 1/16 or 0.0625
Explanation:
As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.
For Branchydactylus and For tasting : man and women will be heterogeneous.
Hence,
The Genotype of man = BbTt
The Genotype of wife = bbTt
b. Answer = 0.0625
For Branchydactylus:
Bb X bb
Possible genotypes:
B b
b Bb( Brachydactylus) bb(normal)
b Bb (Brachydactylus) bb (normal)
The probability of a single child being Branchydactylus = 2/4 = 0.5
So, Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625

what is cell differentiation?
Answer:
The process through which a cell transforms from one cell type to another is known as cellular differentiation. In most cases, the cell transforms into a more specialized form. As a multicellular organism develops from a basic zygote to a complex system of tissues and cell types, it undergoes many stages of differentiation.

The Kirkwood gap is a gap with no asteroids as a result of the gravitational pull of____.
The Kirkwood gap is an asteroid belt region situated between the orbits of Mars and Jupiter that has a significant depletion of asteroids. This chasm is caused by Jupiter's gravitational pull, which causes asteroids to move around and destabilase their orbits.
What is Kirkwood gap?The Kirkwood gap is an asteroid belt region located between the planetary orbits of Mars and Jupiter that has a significant depletion of asteroids. This chasm is caused by Jupiter's gravitational pull, which causes asteroids to migrate and destabilize their orbits.
Jupiter's gravity has a major influence on the asteroid belt, causing their orbits to grow unstable and potentially crash with other objects. As a result, asteroids in some asteroid belt regions may be expelled from their orbits or smash with other things, leaving gaps or areas with fewer asteroids.
The Kirkwood gap was named after the American scientist Daniel Kirkwood, who first observed the decrease of asteroids in this region in the year 2000.
Therefore, the Kirkwood gap is an asteroid belt region situated between the orbits of Mars and Jupiter that has a significant depletion of asteroids.

different seeds need different cultivation. justify in 200 words.
for 18 points
Answer:
Cultivation is the process of growing crops. we need different seeds to cultivate different types of food. Similarly, different seeds need different cultivation. For eg: we grow potatoes in well-drained loam soil. But we grow rice in muddy soil. Every seed has a different way to produce food. They need different temperate or climates, different types of soil, to grow them. They have their own time or season to grow and produce food. If we try to grow plants or vegetables in the wrong season or the wrong process, then we can't get a good result. For eg: If we try to grow rice in drained soil then it will not give us a good result or if we try to grow potatoes in muddy soil we cant get our good result.
So, we can say that different seeds need different cultivation.

b) Describe two measures each to conserve natural vegetation and wildlife, Class 8 - Geography - Unit 1 betwen 90to100 words
Answer:
Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.
Explanation:
The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.
So, we need to plant more trees that act as the natural habitat for the wildlife and preserve and conserve them in parks and sanctuaries which will help reduce the impacts of global warming and climate change. We should not kill any animal.We should decrease the use of plastics.Which radioactive isotope would you use to date a 4-billion-year-old piece of granite?

draw a flowchart showcasing the process of scientific learning .also mention a short description of each of the step in the chart.
Answer:
The scientific method is a system of exploring the world around us, asking and answering questions, and making predictions. Scientists use the scientific method because it is objective and based on evidence. A hypothesis is fundamental to the scientific method. A hypothesis can take the form of an explanation or a prediction. There are several ways to break down the steps of the scientific method, but it always involves forming a hypothesis, testing the hypothesis, and determining whether or not the hypothesis is correct. If the hypothesis is rejected, this does not mean the experiment was a failure. In fact, if you proposed a null hypothesis (the easiest to test), rejecting the hypothesis may be sufficient to state the results. Sometimes, if the hypothesis is rejected, you reformulate the hypothesis or discard it and then go back to the experimentation stage.
The process of scientific learning refers to the various steps via which one can examine and study our environment to understand it. Once understanding or know-how is achieved, then technology is said to have advanced further.
It starts with making observations. Now because of the limitation of our senses, it is important not to jump to conclusions. The next step is to form a hypothesis based on the observation madeWhen you have arrived at a hypothesis, you can now carry out a controlled experiment where you collect further data and reach conclusions based on the experimentIf the hypothesis is in line with your observation, you publish resultsIf the hypothesis is null, you also publish results, then review your hypothesis and repeat the experimentAll the above require consistent documentation at each stage. Please see the attached image for the flowchart.

Explain how 2 polynucleotides can twist helically around each other to form a double helix of DNA?
Explanation:
The antiparallel arrangement of the two strands is what causes the twist. Because the strands run in opposite directions, they pull the sides of the molecule in opposite directions, causing the whole thing to twist around itself. Most naturally occurring DNA spirals clockwise.
