which of the following types of transport moves molecules from a higher concentration to an area of a lower concentration by use of protein? a.diffusion b.osmosis. c.facilitated diffusion d.active transport

The process of transport across cell membranes which costs biochemical energy is known as active transport.

Active transport is a type of cell membrane transport process that necessitates the use of ATP energy to transport molecules or ions against their concentration gradient. Active transport is used by cells to transport molecules across cell membranes. There are two types of active transport: primary active transport and secondary active transport. Primary active transport relies on ATP, which is converted to ADP, to power the movement of molecules or ions against their concentration gradient. It can be accomplished by pumps or transporters that span the cell membrane. Secondary active transport is distinct from primary active transport. Instead of ATP, it relies on the electrochemical gradient generated by primary active transport to transport molecules or ions against their concentration gradient. The potential energy from the electrochemical gradient is used to power the movement of molecules or ions.

Answer:

hypothalamic-pituitary-adrenal axis

Explanation:

The hypothalamic-pituitary-adrenal axis (HPA axis) connects the central nervous system and the endocrine system. They work together to adjust the balance of hormones to affect stress response.

Active transport is a cells way of transporting materials that uses energy.

Active transport is a type of passage through the membrane in which energy is expended for transport to occur. There is a movement of molecules from a region where there is a lower concentration of this molecule to where there is a higher concentration, which is against the concentration gradient.

When overcoming a force, it will need energy to be able to generate this transport, so the transport proteins will need ATP to generate this movement of molecules.

One of the best known molecules that performs this type of transport, and one of the most important in the cell to maintain ion homeostasis inside and outside the cell, is the sodium-potassium ATPase pump, which pumps sodium ions out of the cell and pumps potassium ions into the cell.

Therefore, we can confirm that active transport is a cells way of transporting materials that uses energy.

The statement that “ pathogenic microbial agents include bacteria, worms, protozoa, viruses, fungi, and heavy metals ” is false.

Pathogens are microscopic organisms that have the ability to enter the body and can be a source of disease for the body. It includes tiny living organisms which are not visible to the normal eye. As the pathogens definition includes only living organisms therefore heavy metals are not included in the group of pathogens while bacteria, worms, protozoa, viruses, and fungi are considered to be pathogens since they are living organisms and have the ability to penetrate into hosts and can cause a disease or illness.

However, if the levels of heavy metals are too high in the body, they can be dangerous for the body as they have an adverse effect on many different organs.

Explanation:

The structures that I observed under magnification help the organisms carry out basic functions of life in a variety of ways. For example, the cell membrane helps to control what enters and leaves the cell, the nucleus contains the cell's DNA, the mitochondria produce energy, and the chloroplasts produce food for plants.

The cell membrane is a thin layer that surrounds the cell and protects it from its environment. It also controls what enters and leaves the cell, allowing only certain molecules to pass through. This is important for maintaining the cell's internal environment and for carrying out essential functions such as nutrient transport and waste removal.

The nucleus is the control center of the cell. It contains the cell's DNA, which is the genetic material that determines the cell's structure and function. The nucleus also contains proteins that are involved in DNA replication, transcription, and translation.

Heterozygous individuals exhibit a third phenotype that sits in the middle of the two other phenotypes.

The dominant alleles do not completely outnumber the other in these instances. It is only expected that the entire offspring will be Palomino when a chestnut individual is crossed with a diluted individual. The intermediate phenotype has a 100% chance of being obtained in these instances. However, there is only a 50% chance of producing a palomino offspring when crossing two palomino individuals.

option A is correct answer hope it helps

Answer:

Explanation:

Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.

The reduction is accomplished by 2 divisions after the duplication of chromosomes

- first division: separation of homologous pairs of chromosomes (this reduces the total in half)

- second division: separation of sister chromatids of a chromosome.

The rearrangement in meiosis occurs by crossing over/genetic recombination.

This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation

An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.

This condition produces offsprings that have some characteristic facial features, short stature etc

Rearrangement takes place at the time of meiosis with the lining of chromosomes pair during the metaphase 1 and 2. Down syndrome is the example of chromosomal abnormality.

• A process in which a single cell differentiates two times to generate four cells comprising half the original amount of genetic information is termed as meiosis.

• During meiosis, the process of rearrangement takes place when the chromosomes line up in pairs at the time of metaphase 1 and 2. Then in anaphase 1 and 2, the separation of these chromosomes takes place and each gamete gets one of each kind of chromosome.  

• One of the examples of chromosomal abnormality is Down syndrome, which is, illustrated by the third copy of chromosome 21. The phenotypic variability, which takes place during Down syndrome is muscle hypotonia at the time of birth, and cognitive impairment.  

Thus, during meiosis reduction and rearrangement of chromosomes takes place, and one of the chromosomal abnormality is the Down syndrome.

This investigation examined the effects of programmed aerobic exercise on protein metabolism in children (n = 7; mean ± SEM: 9.14 ± 0.46 y old; weight, 32.1 ± 1.6 kg; height, 138 ± 2.5 cm; and body mass index, 16.21 ± 0.36 kg/m2 ) using 15N-glycine methodology. Boys (n = 5) and girls (n = 2) walked (5 d/wk, 3.2–6.4 km/d) for 6 wk. Criterion measures taken at baseline (Pre) and after the exercise program (Post) included anthropometric data, dietary assessment, nitrogen balance, nitrogen flux (Q), protein synthesis (PS), protein breakdown (PB) and net protein balance [(Net) = PS − PB]. After the walking program, there were no significant changes in body weight, fat-free mass or percentage of body fat, whereas height increased (P < 0.01). Energy and protein intakes were constant throughout the study. Nitrogen balance was significantly more positive Post than Pre (P < 0.05). There was a significant decrease in Q (P < 0.0001) with corresponding decreases in PS (P < 0.001) and PB (P < 0.01). These data provide the first evidence that programmed aerobic exercise alters whole-body protein utilization in healthy, nonobese children. Longitudinal studies are required to further examine changes in protein metabolism associated with increased physical activity in this population. In addition, findings suggest a need to evaluate nutrient requirements for healthy, physically active boys and girls.

Carbon is an element with four valence electrons which makes it possible to

form covalent bonds with other elements such as Hydrogen, oxygen etc.

Carbon has four valence electrons and needs an additional four in order to

achieve a stable octet configuration. This makes it react with other

elements . When an element has fewer or no valence electrons in the outer

shell, it becomes less reactive to ensure the stable configuration isn't altered.

This is why carbon is able to pair electrons with other elements through

covalent bonding to ensure that the octet configuration is achieved.
