Can Someone Answer These 2 Questions For Me?

Answers

Answer 1

Answer:

18 Answer: Hypothalamus, Pituitary and Gonads (Testis and Ovary)

19 Answer:

GnRH (Gonadotropin Releasing Hormone) secreted by hypothalamus

LH (Leutinising Hormone) and FSH (Follicle Stimulating Hormone) secreted by Pituitary Gland

Estrogen (released by ovary) and Testosterone (released by Testis)

Explanation:

GnRh stimulates pituitary gland to release LH and FSH

LH or leutinising hormone facilitates maturity of gonads (testis and ovaries) and production of gametes.

FSH stimulates ovulation and has deep influence no menstrual cycle in female.

In a large population of approximately 1 million E. coli , one bacterium gains a mutation that gives it a fitness advantage , with a selective coefficient of . Which of the following statements is FALSE ? s = 0.001 Given the population size , the selective coefficient is large enough to overcome genetic drift . It is possible that the mutation could be lost from the population due to genetic drift . The mutation will likely sweep through the population to fixation if the individual has offspring with the new mutation Ans = 0.001 would not be considered large given that population size .

Answers

It is considered "fixed" inside the population that once frequency of a allele reaches 100%, i.e., is the only genetic variant present in either member.

What do you name a gene that is fixed inside the population due to a mutation?

December 2020) An allele is considered permanent if it is the only variety of that gene in the population. The entire population is heterozygous for a fixed allele. The term "allele" typically refers with one variant gene from out numerous that could exist for a specific Genomic region.

What impact does population size have on these alleles' time to fixation?

The likelihood of fixation increases because individuals with the mutant gene are much more likely to reproduce in a population that is expanding. Since it's more rare and more apt to be established, the allele has a lower risk of being lost.

A cell is placed in a hypertonic solution. Which will most likely occur as homeostasis is maintained in the cell?.

Answers

Answer:

shrivel and die

Explanation:

A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis. An isotonic solution is any external solution that has the same solute concentration and water concentration compared to body fluids. In an isotonic solution, no net movement of water will take place.

Which of the following is a benefit of using chemical signals rather than electrical signals to send messages to the next neuron?
O Electrical signalsO interneuronO hippocampus

Answers

Electrical signals are not strong enough to get through the synaptic cleft. Neurons are too far apart for an electrical signal to travel. The variety of responses produced can be expanded due to the simultaneous release of many neurotransmitters. These are the advantages of using chemical impulses rather than electrical signals.

What are neurotransmitters?

Neurons use neurotransmitters to interact with one other and their target tissues during the synaptic transmission process (neurotransmission).

Nerve endings synthesize neurotransmitters, which are then released from them into the synaptic cleft. From there, receptor proteins in the cellular membrane of the target tissue bind to neurotransmitters. The target tissue is stimulated, blocked, or otherwise functionally altered.

Among the more than 40 neurotransmitters found in the human neurological system, acetylcholine, norepinephrine, dopamine, gamma-aminobutyric acid (GABA), glutamate, serotonin, and histamine are some of the most significant.

What is synaptic cleft?

The synapse contains a space called the synaptic cleft. It is a component of the neural network. It refers to the region where neurotransmitters move back and forth between neurons. The synaptic cleft, which is a component of the neural pathway, aids in facilitating communication between the brain and nervous system.

How does oxygen bind to the hemoglobin?

Hemoglobin molecule has four binding sites for oxygen molecules, iron atoms in the four heme groups and thus, each Hb tetramer can bind four oxygen molecules. From molecular weight of Hb, it is calculated that 1 g of Hb can combine with 1.39 ml of oxygen.

Oxygen is one of the substances transported with assistance of red blood cells and RBC contains a pigment called hemoglobin and each molecule of which binds four oxygen molecules. Oxygen molecules are carried to individual cells in the body tissue where they are then released.
