Answers

Answer 1

Answer:

The extensor digitorum communist muscles extend the WRISTJOINT.

Explanation:

extensor digitorum communis muscle is an important muscle that is found at the backside or posterior compartment of the forearm.

It originates from the lateral epicondyle of humerus to the medial four phalanges of the hand.

The muscles help in hand and elbow movement.

This muscle give extension to finger 2 and 5 that is phylanges, hand and wrist. It also three extensor carpi muscles.

Answers

Answer:

Explanation:

The binding affinity in ligand binding is measured using the equilibrium dissociation constant (KD).

The larger the dissociation constant value, the more weakly the target molecule and ligand are attracted to and bind to one another.

Explanation:

The hypothalamus is a small part of the brain located at it's base near the pituitary gland. It has three main regions and each region contains different nuclei. These neurons perform different important functions in controlling the many physiological processes and in the maintenance of homeostasis in the body. Five of such processes that are regulated by the hypothalamus include;

1) The hypothalamus regulates the release of hormones by producing hormone releasing factors which trigger or inhibit the release of hormones form other parts of the body.

2) Regulation of body temperature.

3) Regulation of blood pressure and heart rate.

4) Regulation of appetite and weight control.

5) Regulation of the volume of body fluids.

Which of the following describes a benefit of membership in a research community?

Answers

Answer:

knowledge and valuable resources are shared among scientists

Explanation:

The best benefit and reason for joining a membership in a research community is that knowledge and valuable resources are shared among scientists. Since the entire community is working towards a common goal, then gaining information from everyone in order to get closer to that goal is priceless. Also, the ability to use high-end resources that would be impossible to use as a lone scientist due to its high price is also a very valuable benefit.

A circular double-stranded DNA molecule contains 4200 base pairs. In solution, DNA is in a B-form helix, with about 10.5 base pairs/turn. The DNA has 12 superhelical turns. What is its superhelix density

Answers

Answer:

The correct answer is - 3 × 10⁻²

Explanation:

first find LKo = length of BDNA/ 10.5 bp/turn

= 4200/10.5

= 400

now calculate Δ LK= LK - LKo

ΔLK = 412-400

ΔLK = 12

now, superhelix density  = ΔLK/LKo

⇒ 12/400 = 0.03

= 3×10⁻²

Thus, the correct answer is - 3 × 10⁻²

what is a part of interphase A. cytokinesis B. telophase C. anaphase D. s phase

Answers

Answer:

D

Explanation:

I did it on my own soci know it's the answer

In the context of interphase, the S phase is the specific part where DNA replication occurs, contributing to the overall process of cell division and ensuring the transmission of genetic material to new cells and the correct option is option D.

Interphase is the longest phase of the cell cycle, and it is divided into three main stages: G1 phase, S phase, and G2 phase. Among these stages, the S phase is specifically responsible for DNA replication. It is during the S phase that the cell's DNA is duplicated in order to prepare for cell division.

During the S phase, the DNA helix unwinds, and the two strands separate. Enzymes and proteins then work together to synthesize new complementary strands for each of the separated DNA strands. As a result, two identical copies of the DNA molecule are produced.

The S phase plays a crucial role in maintaining the genetic integrity of the cell. By accurately duplicating the DNA, the cell ensures that each daughter cell formed during cell division receives an identical set of genetic information. This is vital for the proper functioning and development of organisms.

Thus, the ideal selection is option D.

Explanation:

What is the difference between an excitatory postsynaptic potential and an inhibitory postsynaptic
potential?​

Answers

Answer:

A postsynaptic potential is defined as excitatory if it makes it easier for the neuron to fire an action potential. ... A postsynaptic potential is considered inhibitory when the resulting change in membrane voltage makes it more difficult for the cell to fire an action potential, lowering the firing rate of the neuron.

Bu definition, the difference between an excitatory postsynaptic potential and an inhibitory postsynaptic potential is the ion channels that these open.

The binding of neurotransmitters to their receptors can produce different effects on the postsynaptic neuron, including the opening of ion channels. This causes changes in the membrane potential and leads to the generation of postsynaptic potentials. These postsynaptic potentials can be of two types: postsynaptic excitatory potentials and postsynaptic inhibitory potentials.

In other words, depending on the type of ions that allow the receptor-channels or channels that were activated directly or indirectly by the neurotransmitter to pass, the postsynaptic potential generated may be depolarizing (excitatory postsynaptic potential) or hyperpolarizing (inhibitory postsynthetic potential).

The inhibitory postsynaptic potential changes the charge of the neuron to make it more negatively charged, that is, the membrane potential becomes more negative (hyperpolarizations).

In contrast, an excitatory postsynaptic potential is a change in the electrical charge of a nerve cell or neuron. The neuron begins with a negative charge, but the excitatory postsynaptic potential makes this charge more positive, that is, the membrane potential becomes less negative (depolarization).

So the difference between an excitatory postsynaptic potential and an inhibitory postsynaptic potential is the ion channels that these open. The binding of neurotransmitters to their receptors can produce different effects on the postsynaptic neuron, including the opening of ion channels. This causes changes in the membrane potential and leads to the generation of postsynaptic potentials.

Implanting an electrode that supplies a weak electrical current to specific brain areas is called _____. It is useful in the treatment of _____

Answers

Answer:

Deep Brain Stimulation (DBS)

Depression, Uncoordinated body movements such as in Parkinson's disease

Explanation:

Deep brain stimulation is a surgical procedure in which a device that sends electrical impulses to the brain by means of lead wires connected to electrodes placed in the specific areas of the brain, is implanted in the body, typically the chest region.

This surgical procedure is usually required to treat diseases in which there is irregular and improper nervous stimulation of the brain resulting in various nervous disorders such as irregular muscle movements as in Parkinson's disease as well as depression.

The impulses sent from the stimulator device to the electrodes in the brain through the wires, serves to stabilize and normalize nerve signals sent to the brain.
