Answer:
C
Explanation:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. (REDUCING) its making more and more

what are the types of gametes
Answers
In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile. The haploid condition of the two gametes is essential so that at fertilization during sexual reproduction the integrity of the chromosomal number is maintained throughout generations.
Hope this helps.
Answer:
Examples of Gametes. The two most common gametes are sperm and ova. These two haploid cells can undergo internal or external fertilization and can differ from each other in size, form, and function. Some species produce both sperm and ova within the same organism

Answers
Answer:
Guy on top is correct. It is 100%
Explanation:
As predicted by the Punnett square, 100% of the offspring have black fur for this cross.
When two individuals with the genotype BB (homozygous dominant for black fur color) are crossed, their Punnett square will look like:
| B | B
--|----|----
B | BB | BB
--|----|----
B | BB | BB
All the offspring will have the genotype BB, which means they will be homozygous dominant for black fur color. Therefore, all the offspring will have black fur.

Which statement is an accurate description of genes? A) Proteins are made of genes and code for DNA B) Genes are made of proteins that code for nitrogen bases C) DNA is made of carbohydrates that code for genes D)
Genes are made of DNA and code for proteins.
Answers
Answer: The correct option is D.
Genes are made of DNA and code for proteins.
Explanation:
This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.
DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.
A population of birds lives on a small island. Another population of the same species lives on the mainland. The distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of sandbars and tiny islands have formed between the island and the mainland. What is the most likely effect of this?
Answers
Answer: An increase in gene flow between the bird populations.
Explanation:
The population of bird species living in the island and other one in mainland are geographically isolated because of the distance between the island and the mainland is large that does not allow birds to fly and cover the entire distance. This is the reason of reproductive isolation and restricts the gene flow between the two populations. But the creation of sandbars and tiny islands between the island and mainland created a way so that island and mainland birds can meet and reproduce. This will allow the increase in the gene flow between the two separated population of bird species.

Which statement best describes the flow of energy and the movement of chemical compounds in an ecosystem?
Energy flows out of living organisms and is lost, while chemical compounds remain permanently inside organisms.
Energy is transferred from organism to organism in a food chain, and chemical compounds are recycled
Energy flows into living organisms and remains there, while chemical compounds are transferred from organism to organism.
Chemical compounds flow in one direction in a food chain and energy is produced.
Answers
Answer:
This is because in biology, energy is transferred from organism to organism and some energy is lost along the way. Each energy transfer results in a loss of energy, so that energy is always at a lower level and can never be returned to its original high energy level. On the other hand, chemical elements can form products, then that reaction can be reversed and break back down into reactants. Additionally, the law of conservation of matter says that matter can't be created or destroyed, only transferred from one form to another.
Answer:
C
Explanation:
Energy flows while matter cycles
