Plants grown from runners and leaf cuttings have the same traits as the parent plant. Plants grown from seeds can vary from the parent plants in many ways. Why can this happen?
Answers
Explanation:
Plants produced from asexual reproduction are the result of mitosis, so they are genetically identical.
Asexual reproduction produces plants that are genetically identical because they are the result of mitosis.
What is asexual reproduction?Asexual reproduction is a type of reproduction that does not involve gamete fusion or chromosome number changes.
Asexually reproduced offspring from either unicellular or multicellular organisms inherit the entire set of genes from their single parent.
Asexual reproduction is also possible in yeast, fungi, plants, and bacteria. Yeast most commonly reproduce by budding.
Plants and fungi reproduce asexually via spores. Plants can indeed procreate asexually through vegetative propagation.
Asexual reproduction is significant because it allows for a rapid and significant increase in the number of individuals.
Many weeds and invasive species, for example, thrive in part due to their high capacity for vegetative reproduction.
Thus, the plants grown by seeds will have genetic variation due to meiosis in the cells. The runners will be identical to the parents as they will undergo asexual reproduction.

A.
Brown Hair
B.
Blonde Hair
C.
Brown and Blonde Hair
D.
Black Hair
Answers
Answer: His phenotype will be Bb. He will have brown hair because it is a dominant trait.
Explanation: Heterozygous indicates that there are two different genes present in a genotype (Bb instead of BB or bb).
Mark's phenotype will be Brown hair because he is Bb i.e. heterozygous.
What is phenotype?The term phenotype simply refers to a trait that may be observed.
Pheno means observe.
The observable qualities or traits of an organism resulting from the interplay of genetics and environment i.e. one or more genes physical expression.
What is heterozygous?At a given gene locus, the existence of two distinct alleles.
One recessive gene and one dominant gene or two separate mutated alleles, can make up a heterozygous genotype.
so, the Mark's phenotype will have brown hair because he is heterozygous thus contain Bb and B is responsible brown hair which is dominant over gene b which is recessive and responsible of blonde hair.
Hence, the correct answer is A.

How do fish increase lake carbon dioxide levels?
Answers
Answer:
The primary sources of carbon dioxide in fish ponds are derived from respiration by fish and the microscopic plants and animals that com- prise the fish pond biota. Decomposition of organic matter is also a major source of carbon dioxide in fish ponds.
Fish can play a role in mitigating the accumulation of CO2 in aquatic ecosystems through Photosynthesis, Respiration, Organic Matter Decomposition, and Carbon Sequestration.
The carbon cycle in lakes and the role of fish within it:
1. Photosynthesis:
Aquatic plants, including algae and submerged vegetation, undergo photosynthesis, which involves using sunlight, carbon dioxide, and water to produce oxygen and organic carbon compounds. This process helps to remove CO2 from the water.2. Respiration:
Fish and other aquatic organisms respire, consuming oxygen and releasing CO2 as a byproduct. However, the amount of CO2 produced by respiration is typically balanced by the oxygen produced through photosynthesis.3. Organic Matter Decomposition:
When plants and animals die in the lake, their organic matter sinks to the bottom, where it is decomposed by bacteria and other microorganisms. This decomposition process consumes oxygen and releases CO2.4. Carbon Sequestration:
Some of the organic carbon compounds produced by photosynthesis can be stored in the lake sediment, effectively sequestering carbon for extended periods.Thus, through photosynthesis, respiration, the breakdown of organic matter, and carbon sequestration, fish can mitigate the accumulation of CO2 in aquatic environments.

divides once
divides twice
2 daughter cells
4 daughter cells
Answers
Answer:
With respect to mitosis it is true that:
Daughter and parent cells have the same number of chromosomes.Divides once.2 daughter cells.Explanation:
Mitosis is the process of cell division that occurs in somatic cells, resulting in two daughter cells identical to the original cell, that gave rise to them. This process occurs because of the need of organisms to grow, develop, regenerate and repair themselves.
Somatic cells are diploid cells —full chromosome charge— and the result of their mitotic division are diploid daughter cells. The process of mitosis occurs only once during each cell cycle.
The other options correspond to meiosis, where from one cell haploid daughter cells are obtained, two successive divisions occur - meiosis I and II, the final result being 4 cells.

B. Replace "stroma" with "chlorophyll."
C. Exchange the positions of "stroma" and "grana."
D. Exchange the positions of "thylakoid" and "stroma."
Answers
Answer:
C. Exchange the positions of "stroma" and "grana."
"A chloroplast contains thylakoid stacks, called grana, that are surrounded by fluid-filled stroma."
Explanation:
A dynamic biochemical process, photosynthesis, occurs within the chloroplasts of plants. Here, to form stable carbohydrates, light energy is transformed into chemical energy.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Chloroplasts are tiny, highly-folded, membrane-bounded organelles containing enzymes, pigments and other molecules that mediate photosynthesis. In the stack of grana, pigments like chlorophyll, absorb light energy for the light-dependent reactions.

DNA, the RNA polymerase core enzyme, and the subunit are the first transcriptional components. mRNA, small and large ribosomal subunits, initiation and elongation factors, as well as tRNA, are all parts of the translation process. Thus, option D is correct.
What are the factor affecting the process of transcription?Proteins called transcription factors are involved in the process of turning DNA into RNA, or transcribed DNA.
A large variety of proteins—aside from RNA polymerase—called transcription factors start and control how genes are transcribed.
A gene's transcription is boosted by transcription factors that serve as activators. Reducers lessen transcribing.
An enhancer or silencer is a collection of transcription factor binding sites that can turn a gene on or off in a particular region of the body.
Therefore, Transcription is the process in which a strand of DNA is used as a template for the manufacture of a strand of pre-mRNA.

Why is this statement false? “The amount of carbon on our entire planet can increase or decrease depending on the fluctuations of the carbon cycle.”
Answers
Answer:
False because the carbon cycle is the process by which the carbon in the atmosphere of earth is exchanged and released in the biosphere and atmosphere of the earth. So basically, the amount of carbon is increased or decreased by the burning of fuels and not by the fluctuation of the carbon cycle.
The statement is false due to the fact that carbon does not decrease or increase due to the fluctuation of the carbon cycle.
Carbon flux in the carbon cycleThe level of carbon in the carbon cycle changes based on both natural and anthropogenic processes.
The natural processes include respiration, photosynthesis, and volcanic eruption while anthropogenic processes include the burning of fossil fuels, usage of emission technology, etc.
These processes lead to the addition and fixation of carbon from the cycle.
Thus, the cycle itself does not fluctuate but the level of carbon in the cycle.
