Arecent study has shown an increase in the number of predators in an ecosystem. Which of the following is a possible
cause for the growth?
A) a decrease in the land space available
B) an increase in the population of prey it feeds on
C) a decrease in the biodiversity of the ecosystem
D) an increase in the number of predators that feed on it
E) an increase in the plant life in the ecosystem
PLS HELP ASAP
Answers
Answer:
The correct answer would be - B) an increase in the population of prey it feeds on.
Explanation:
In an ecosystem, if there is an increase in the number of predators there are several possible conditions behind it. The most suitable and important factor that can lead to this is an increase of prey they rely on.
If there is an increase in numbers of prey in the particular ecosystem then there would be more food and resources for predators which help in growing the development of predators.

4 sentences.
Answers
Given their unique regenerative abilities, stem cells offer new potentials for treating diseases such as diabetes, and heart disease. Research on stem cells continues to advance knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms.
Yes. Without stem cell research there would be alot more sick people. There would be alot more sick people because Stem-cell research is an area of research that studies the properties of stem cells and their potential use in medicine. As stem cells are the source of all tissues, understanding their properties helps in our understanding of the healthy and diseased body's developmental and homeostasis. Stem cells originate from two main sources: adult body tissues and embryos.

Answers
Answer And Explanation:
The advantages of asexual reproduction compared to sexual reproduction include the population being able to increase rapidly when the conditions are in their favour, only one parent is needed, it is more time and energy-efficient due to not needing a mate and it is faster than sexual reproduction.

Which statement best describes how the environment influences the traits of an individual?
The environment influences the gene expression which can change the genotype.
The environment influences the gene expression which can change the phenotype.
The environment influences only external factors.
The environment influences only internal factors.
Answers
Answer: The environment influences the gene expression which can change the phenotype.
Explanation: TRUST
The environment influences the gene expression which can change the genotype. The correct option is A.
What is gene expression?The methodology by which a gene in a cell is activated to produce RNA and proteins.
Gene expression can be assessed by examining the RNA, the protein produced from the RNA, or whatever the protein does in the cell.
The environment can impact gene expression in a life form, along with the outer environment in which the species is positioned or evolves, as well as the organism's internal world, which encompasses factors such as hormones and metabolism.
Several factors influence gene expression, which would include molecules within the cell, mutations that cause dominant damaging consequences and haploinsufficiency, signaling molecules from neighboring cells and the environment, and epistasis.
The environment influences an individual's genotype but not his or her phenotype.
Thus, the correct option is A.

In Rabbits, black fur (B) is dominant to white (b), and long ears (E) are dominant to short ears (e). What is the expected phenotypic ratio of the offspring of a BBee x bbEE cross if these alleles sort independently?
Answers
Answer:
A. 16 black/long ears, 0 black/short ears, 0 White/long ears, 0 White/short ears
Explanation:
This question is a typical dihybrid cross i.e. involving two genes in rabbits. One coding for fur color and the other for ear length. The allele for black fur (B) is dominant to allele for white fur (b) and allele for long ear (E) is dominant to alelle for short ear (e).
In this question, a cross between two rabbits with genotypes: BBee x bbEE is performed. The following combination of gametes will be produced by each rabbit:
BBee - Be, Be, Be, and Be
bbEE - bE, bE, bE, and bE
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
All BbEe offsprings, which have a black fur and long ear phenotype.
Hence, the phenotypic ratio is 16 black/long ears, 0 black/short ears, 0 White/long ears, 0 White/short ears

Answers
Answer: the order of base pairs
Explanation: i took this quiz lol
l
The only difference in the chemical structure of DNA between various organisms is the order of base pairs that is present in the second option. The order of base pairs is different in different organisms.
What is the base-pair role present in the DNA?There are two DNA strands in double-helical DNA that are linked together by hydrogen bonds, such as adenine's double hydrogen bond with thymine and guanine's triple bond with cytosine. All the organisms that belong to different species have the same bases and same nucleotides, such as ATP, GTP, CTP, and TTP, but the base pair order is different, and that makes them unique. The gene having some specific sequences in an animal is different from the gene of another animal, and this is due to the various base pairs in the DNA.
Hence, the only difference in the chemical structure of DNA between various organisms is the order of base pairs that is present in the second option.

Which statement best describes the result of meiosis?
A.

B.
It causes alleles to deform.
C.
It prevents genetic mutation.
D.
It produces reproductive cells.
Answers
Answer: The correct answer is D. It produces reproductive cells.
Explanation: Confirmed correct.
The statement that best describes the result of meiosis is it produces reproductive cells. The correct option is D.
What is meiosis?Meiosis is a reduction division, thus the sex cells that create the gametes will do so while going through meiosis. The number of chromosomes in the gametes will be halved from that of an adult human.
A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells—sperm in men and eggs in women—are our sex cells.
Four haploid daughter cells with chromosomal variations from the original parent cell and half as many chromosomes as the original parent cell are the result of meiosis (diploid).
Therefore, the correct option is D. It produces reproductive cells.
