Answer:
C. Cutting down forests.
Explanation:
Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.
The effects of an increase in CO2 concentration in the atmosphere is as follows:
- increase in water contamination and floods
- ocean acidification
- reduction of cold-related deaths
However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.

How does artificial selection cause rapid changes in the phenotypes of organisms?
A.By selecting dominant genotypes
B.By changing the number of
chromosomes
C.By changing the frequency of alleles and
selecting new combinations of traits
D.By stimulating the species to increase
the production of new mutants
Answer: A. By selecting dominant genotypes
Explanation:
Artificial selection or selective breeding can be defined as the induced breeding process in which humans select parents of plants and animals that have desired traits that are beneficial for them to produce offspring that have characteristics of both parents and they are of improved yield and quality. This brings the change in the phenotypes of the offspring as compared to the parents. As the passage of dominant desirable traits in the genotype from either of the parent when gets expressed then the phenotype of the organism also change.

Which type of reproductive isolation occurs when there are differences in the size or shape of reproductive parts and may prevent interbreeding
Temporal isolation, in biology, a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from mating and producing hybrid offspring.
A prezygotic barrier called temporal isolation promotes speciation, or the creation of new species. Isolation on account of geography, reproduction, or behavior are other prezygotic obstacles.
What reproductive isolation occurs in temporal isolation?A reproductive isolation process known as temporal isolation prevents members of closely related species from mating and producing hybrid offspring.
Temporal isolation occurs when essential reproductive activities occur at different times in sexual organisms.
When two or more species reproduce at different times, this is known as temporal isolation. For instance, three different orchid species might be found in the same rain forest.
Therefore, Each species possesses one-day-only blooms that need to be pollinated on that day in order to produce seeds.

The leaves of plants have layers that perform different functions. The_____ layer contains chlorophyll which carries out most of the photosynthesis in the leaf.
Answer:
The palisade layer
Explanation:
The palisade mesophyll layer of the leaves is a layer of columnar cells that contain many chloroplasts. This layer is localized right below the epidermis and cuticle of a leaf. The chloroplasts localized in this layer contain chlorophyll, which is the green pigment used to absorb light in order to carry out photosynthesis.
Yeasts are single-celled eukaryotic organisms. Yeasts undergo mitotic division when conditions are favorable. When limited nutrients are available, yeasts start dividing by the process of meiosis.
What is a likely reason for the change from mitosis to meiosis during reproduction under these conditions?
The process of meiosis produces greater numbers of yeast cells at a faster rate as compared to mitosis.
Crossing over of genes during meiosis increases diversity and the chance of survival of the next generation.
Duplication of genes during meiosis ensures efficient functioning of the newly formed yeast cells.
The yeast cells formed by meiosis are able to adapt as well as the parent cell because they are identical.
Yeasts change from mitotic to meiotic division when conditions are unfavorable because meiosis increases genetic diversity and improves their chances of survival in unfavorable conditions.
During meiosis, crossing over of genetic materials between non-homologous chromosomes creates genetic recombination and makes the resulting offspring to be genetically more diverse than their parents.
The increased genetic diversity will increase the chances of survival of the offspring in a constantly changing environment. In other words, the more genetically diverse a population is, the more their chances of surviving adverse environmental conditions.

Failure of cell division and production of unreduced gametes during meiosis. D. Somatic doubling in the meristem leading to reproductive organs. E. Both A and B are correct. F. Both C and D are correct. G. All the answers are correct.
Answer:
A. Non-disjunction during Anaphase I of meiosis.
Explanation:
Euploidy is an alteration in the organism´s natural number of chromosomes. Individuals with euploidy express a different number of homologous chromosomes set than the one from the normal number.
The cause of this alteration is that homologous chromosomes do not separate during the anaphase of meiosis 1.
There are two types of euploidy:
Polyploidy: Increase in the number of chromosomes characteristic of a diploid complement. During anaphase 1, homologous chromosomes do not separate and migrate together to the same pole. One of the resulting gametes ends with the whole chromosomic material, while the other cell ends with non. The first one goes through the second phase of meiosis and forms two diploid gametes. Monoploidy: Decrease in the normal number of chromosomes. The individual only gets one set of chromosomes. This is a monoploid organism, n.Euploid changes usually takes place as a result of this below developmental errors: is A. Non-disjunction during Anaphase I of meiosis.
Euploidy can be regarded as chromosomal variation which usually take place on the entire set of chromosomes in a cell or an organism.Euploidy can comes in three ways which are;
