Which statement about green plants is true?
Green plants are responsible for water vapor
in the atmosphere.
Green plants are responsible for oxygen in
the atmosphere.
Green plants use photosynthesis, not cellular
respiration
Green plants are primary consumers.
DONE
Answer:
Green plants are responsible for oxygen in the atmosphere.
Explanation:
-Green plants undertake a process of photosynthesis, in which they use energy from the sun, carbon dioxide and water to form simple sugars and also release oxygen to the atmosphere. The simple sugars from the process may be used by the cells for energy or be stored in form of energy for future use.
-Oxygen is a product of photosynthesis which is released to the atmosphere.
Which strophic level does a fish represent in this food chain?
Algae->mosquito larva->dragonfly->fish->man
Answer:
Secondary consumer/small carnivore
Explanation:
The fish is eaten by the top of the food chain/tertiary consumer (human) and eats primary consumers/herbivore (dragonfly), which means it is the secondary consumer on the food chain.
In cats, the long hair trait is dominant and the short hair trait is recessive. What is the chance of a homozygous short-haired offspring if a heterozygous long-haired male mate with a short-haired?
L = Long hair
l = short hair
L l
l Ll ll
l Ll ll
I hope this helped :D
The chances of a homozygous short haired offspring is 50%
The chances of a heterozygous long haired offspring is 50%
The chances of a homozygous long haired offspring is 0%
Answer:
the chance of a homozygous short-haired offspring if a heterozygous long-haired male mate with a short-haired is 50%
Explanation:
The best way to see this is to simply draw a punnett square. As you've said, let's call
S
the dominant trait (short hair) and
s
the recessive trait (long hair):
As shown in the image i uploaded:
As you can see, out of the 4 possible outcomes, 2 will result in short hair, and 2 in long. So, you'd have a chance of getting a short haired cat.
Some scientists have been concluded that the legs of modern land vertebrates evolved from the fins of ancient fish. What most likely provided the evidence for this conclusion?
- study the fossils of ancient land vertebrates
- Identity the numbers of ancient fish and ancient land vertebrates
- comparing the number of genes in modern fish to the number of genes in modern land vertebrates
- comparing the movements of genes in modern fish fins to the limbs of modern land vertebrates
Answer:
1- study the fossils of ancient land vertebrates
Explanation:
Some scientists concluded after performing a number of experiments that the legs of modern land vertebrates evolved from the fins of ancient fish. With the passage of time evolution occurs within the body of organisms. These changes occurs due to the surrounding environmental condition of that organism. When the organisms live in water, fins were present but when they go to the land so these fins change into legs. This type of evidence is provided by the scientist after studying the remains of ancient land vertebrates.

in a recessive disorder, a person will only have the disorder if they have one copy of the allele
True or False
Answer:
False
Explanation:
Since it's a recessive disorder that means the presence of the dominant allele will overshadow the recessive if it's present. Two recessive alleles have to be present in order for the person to have the disorder.

2. Why does the sun and the moon appear to be the same size from Earth?
The sun is 400x wider than the moon, but the moon is also 400x closer to the Earth
than the sun
The moon is bigger than the sun.
The sun changes size throughout Earth's orbit.
They are the same size.
Answer:
The sun is 400x wider than the moon, but the moon is also 400x closer to the Earth
Explanation:
Although the the sun is roughly 400x wider than the moon, the moon is aproximately 400x closer to the Earth, and that is why seen from earth, sun and the moon appear to be the same size.
So answer is the sun is 400x wider than the moon, but the moon is also 400x closer to the Earth.
EXTRA:
There is a fenomenom called blood moon, when that happens, the moon appears to be bigger then normal (and it has a red glow about it).
Where do green plants get there food?
Answer:
Green plants get their food from organic components.
Green plants make their own food by the process of photosynthesis. In this process the chlorophyll present in the leaves trap sunlight.

How doe water change the shape of earth surface?
Answer:
water is constantly moving across the earth. The water is strong enough to break down soil in tiny pieces. What’s happening is a process called erosion. Erosion is: the process of eroding or being eroded by wind, water, or other natural agents.
"the problem of soil erosion".
Water also carries sand and moves it around, this obviously changes the shape of the earths surface!

Explanation:
ldentify the stages of the cell cycle using the drop
down menus
Label A
Label B
Label C
Label D
Label E
Answer:
Label A - G1 (growth phase)
Label B - S phase (DNA synthesis)
Label C - G2 phase (Growth and preparation for mitosis)
Label D - M phase (Mitosis - cell division)
Label E - Interphase
Explanation:
Label A refers G1 phase - In this phase metabolic changes occurs in the cell and cell get prepare for cell division. The cell grow in size only and moves into the S phase.
Label B refers S phase - In this phase DNA synthesis occurs in which genetic material replicates and form two sister chromatids in each chromosome.
Label C refers G2 phase - All the metabolic changes occurred prepare for mitosis and cytokinesis.
Label D refers M phase - In this phase, Mitosis occurs in which nuclear division and cell division (cytokinesis) takes place.
Label E refers to interphase - All the stages from G1 to G2 phases come under the interphase of cell division.
Hence, the correct answers are:
Label A - G1 (growth phase)
Label B - S phase (DNA synthesis)
Label C - G2 phase (Growth and preparation for mitosis)
Label D - M phase (Mitosis - cell division)
Label E - Interphase
Propose some possible explanations for the large volume of noncoding DNA in the human genome.
Answer: Non coding DNA do not contains instructions for proteins synthesis.

What happens during telophase
Answer:
Telophase is the last period of ‘mitosis’ .its a process.
during this process mutation/one or more material is being separated.
Proteins that are embedded forms around each set of chromosomes (a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.). This happens to separate Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid from the cytoplasm.

Scientists have tracked the changes in this land for many years. Picture A shows how the land looked to start with. Many years later, the land looked like Picture B. What MOST LIKELY caused the change in the land?
A) a coastal glacier
B) water cutting the rocks
C) wind blowing in circles
D) earthquakes along the shore
Answer:
D) earthquakes along the shore
Explanation:
Movement of tectonic plates are responsible for reshaping the surface of our planet and it is contributed by earthquake sometime.
High richter scale of Earthquake allow tectonic plates to slide over each other or collide with each other of Earth's crust within a geologically period of time and causes the rising or sinking of the land.
As the image shows uplifting of land and sinking land in picture B, the action is performed by earthquakes along the shore.
Hence, the correct option is D) earthquakes along the shore.

A dihybrid cross is created from plants that are heterozygous for both round seeds and yellow seed color. What is the ratio of offspring that have round seeds and yellow seed color?
Answer:
9:16
Explanation:
The ratio of offspring that have round seeds and yellow seed color in a dihybrid cross is 9 out of 16.
WHAT IS A DIHYBRID CROSS:A dihybrid cross is a cross between two individuals that are are heterozygous for two genes. In this question, a gene involving seed color and seed shape is used. The allele for round shape (R) and yellow seeds (Y) are dominant over wrinkled (r) and green seeds (y).A cross between two dihybrid i.e. RrYy × RrYy will result in the following offsprings:
R_Y_ - 9R_yy - 3rrY_ - 3rryy - 1Therefore, the ratio of offspring that have round seeds and yellow seed color in a dihybrid cross is 9 out of 16.
