can someone answer these 2 questions for me?​

Answer:Animals get the nitrogen they need by eating plants or other animals that contain nitrogen.

Explanation: When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water.

Answer: C. What is the error rate in complementary DNA strand sequences of peony flower after replication?

Explanation: This is a specific and testable question because the student can analyze the DNA sequence of a peony flower before and after replication, and compare the two sequences to determine the error rate in the complementary DNA strands.

Answer:

Depressants are drugs that slow down the central nervous system, leading to reduced brain activity, decreased heart rate, and relaxed muscles.

Explanation:

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.

During experiment, curve changes from sigmoidal to hyperbolic, the following may be the reason for the change : The protein dissociated into individual subunits.

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.

Answer: preventing the replication of DNA

Explanation: overreplication of cells, or extra cells, causes cancer. Stopping the replication of cells can prevent the cancer from worsening. I’ve also had this question on my homework and got the answer correct.

Proteins, lipids, vitamins & minerals are the foods eat to support the chemical processes of human physiology.

The study of how the human body works in both health and sickness is known as human physiology. A degree in human physiology offers good preparation for jobs or graduate school in the health professions, biomedical research, or allied fields.

The study of how organisms carry out their essential activities is known as physiology and comes from the Ancient Greek word phusiologa, which means "natural philosophy."A study of how a muscle contracts or the force that contracting muscles place on the skeleton are two examples.

Several forms of human physiology can be distinguished:

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.

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.

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.

Proteins are attached to the extracellular matrix, the cell cortex, and obstacles such tight junctions.

Identification, communication, control of solute exchange across the membrane, and separation of the nucleus from the surrounding environment are the four primary roles of the plasma membrane.

The membrane that encloses a cell's organelles and serves as a partition between them and the outside world is referred to as the plasma membrane. Every live cell has a thin membrane called the plasma membrane that surrounds it and isolates it from its surroundings.

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.

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.

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.
