solmaris [256]3 years ago
6 0

The correct answer is: A) GABA

GABA or γ-aminobutyric acid is a type of amino acid that's found in proteins. It is the main inhibitory neurotransmitter in the brain which means that GABA reduces neuronal excitability throughout the nervous system. GABA binds to its receptors that are located on the neuron’s plasma membrane. This binding causes the opening of ion channels that transport chloride ions into the cell or potassium ions out of the cell.

What would be the correct sequencing of DNA to match A, T, T, G, C
Marianna [84]

Answer:

A.

Explanation:

The correct sequencing of DNA nucleotides to match A, T, T, G, C is T, A, A, C, G because the nucleotide matches are: Adenine-Thymine, and Guanine-Cytosine. This works both ways, A-T or T-A, and G-C or C-G. The correct sequence therefore is A.

The drug colchicine inhibits the formation of spindle fibers during mitosis. If you treat dividing plant cells with colchicine,
vekshin1

Answer:

D

Explanation:

During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides.   If spindle fibers do not form, then the chromosomes will not separate during anaphase.

Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.

The scientific method provides the framework for all scientific research, including nutrition science. Choose the statement belo
Andrews [41]

Answer:

1) d. observe phenomenon; generate hypothesis, conduct experiment, accept, reject, or modify hypothesis.

C. A study that compares a aroup of people with diabetes to a similar aroup of people without diabetes is an example of a case-control study.

Explanation:

Scientific method is a step by step procedure ranging from observing a problem to actual experimentation that aims at investigating a problem. The steps involved in the scientific method are as follows:

a)observe phenomenon; This precedes every experiment in the scientific method.

b) generate hypothesis: This is a testable explanation given as a possible solution to the observed problem.

c) conduct experiment: The hypothesis is tested via experimentation.

d) accept, reject, or modify hypothesis: Based on the result of the experiment, the hypothesis can be rejected, accepted or even modified.

Question 2:

Case control study is a type of study design that uses or compares a group of affected individuals (by a disease) called CASES and unaffected individuals called CONTROL. In this case, A study that compares a group of people with diabetes (cases) to a similar aroup of people without diabetes (control) is an example of a case-control study.

Atoms of which element contain 25 protons? magnesium (Mg) aluminum (Al) tin (Sn) manganese (Mn) Which element has an atomic numb
mixer [17]

Answer:

1)Manganese (Mn)

2)Sulfur(S)

Explanation:

Atoms of which element contain 25 protons?

It is Manganese.

The atomic number of an element is the number of proton in the nucleous of an atom of the element. Here proton= 25= atomic number.

The number of proton helps to identify the particular element. In the modern periodic table, the elements are arrange base on how the atomic number is increasing. Then Manganese has atomic number of 25.

✓Which element has an atomic number of 16?

It is Sulfur, as explained earlier, the number of pron in the atom of the sulfur element is 16.
