draw the flow chart showing the sequential order of reproductive stage and fertilization
Answers
The sequential order of reproductive stage and fertilization starts with the
male and female sex cells being produces through meiosis. The male sex
cell which is the sperm is produced in the testes while the female sex cell
which is the egg is produced in the ovary.
During copulation, the sperm cells are released into the vagina which then
swims through the cervix and uterus to the fallopian tubes where the
fertilization occurs.
There is then movement of the zygote formed from the fertilization to the
uterus where development occurs.

Producers, like this plant, take in oxygen and release carbon dioxide during__________, just like animals and other living things
Answers
Answer:
Producers, like this plant, take in oxygen and release carbon dioxide during respiration, just like animals and other living things
Explanation:
why is the concentration of oxygen in the body cells lower than the concentration of oxygen in the alveolus?
A. Alveolus can produce oxygen.
B. The exchange of gases occur in the alveolus.
C. Oxygen is used up for respiration I the body cells.
S. Oxygen diffuses out from the body cells.
Answers
Answer:
i think the answer should be b.
the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!
btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

Answers
Answer:
Sea breezes happen during the hot, summer days due t the unequal heating rate of land and water
Explanation:
Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

"The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration."

Give the genotypes of the parents and offspring of a cross between a black male and a brown female that produces 1/2 black offspring and 1/2 brown offspring.
Show all steps in working of this problem.
Answers
Answer:
What are specialized cells
Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.
What is the dominant allele?The connection between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent. One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.
The Cross between parents is Bb x bb
Gametes- B and b
Offsprings- Bb, Bb, bb, bb
The crossing analysis is attached in the image below.
A person needs two copies of a recessive allele, one from each parent, in order for it to result in a recessive phenotype.
Therefore, Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.

a group of unicellular organisms that live together but have on relationship to one another
Answers
The group of unicellular organisms that live together but have no relation to one another is called colonial organisms.
What are colonial organisms?The organization of cells leads to their efficiency. The organization of cells leads to the formation of tissues and organs which leads to the efficient functioning of an organism.
The organization of cells is not only seen in the multicellular level of organization. It starts from the organization of molecules to form structures like proteins and nucleic acid.
Unicellular organisms are able to live and survive independently and perform all life processes necessary for their own survival. But, bacteria are often found to live together in colonies.
A colony is a group of individual organisms that live close to each other. They live together because they are stronger in a colony. A colony of bacteria can protect themselves, acquire their nutrition or attack a host in a better way.
Therefore, a group of organisms who live close to each other and have no relationship is called colonial organisms.

nucleus...controls all the activities of the cell and carrries the genes
mitochondria..site for respiration that yields energy for the cell
endoplasmic reticulum... protein synthesis and lipids metabolism
vacuoles.... handle waste products and are responsible for regulation of osmotic pressure of a cell also
Explanation:
is this helpful?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

How could the changes made to the amino acid sequence influence phenotype changes?
Answers
A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.
Protein structure ordersThe sequence of a protein is determined by the DNA of the gene that encodes that protein (or that encodes a portion of the protein, for multi-subunit proteins).
A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.
Even changing just one amino acid in the protein sequence can affect the protein's overall structure and function. For example, a single amino acid change is associated with sickle cell anemia, an inherited disease that affects red blood cells.
