Explanation:

Spermatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into an embryo.

What are the negative assay results?

False-negative blocks haven't received as much attention as false positives, but they can lead to misdiagnosis and improper treatment candidate selection. Based on the failure of local anesthetic infiltration to relieve the pain from facet joint capsular distention, research on 15 volunteers who had MBBs with local anesthetic or saline and capsular distention estimated the rate of false-negative blocks to be 11%.

It was determined that "aberrant innervation" was a likely explanation for some instances of unsuccessful RF denervation in IA block responders. Vascular uptake is regarded to be one of the main sources of false-negative blocks. According to reports, this can vary from 6% to 30% per level. rates of 3.9% at cervical levels, 3.5% at lumbar levels, and 0.7% at thoracic levels, according to one research.

According to one study, even if the needle is relocated when vascular uptake happens, analgesia will only be experienced 50% of the time. Digital subtraction angiography has been demonstrated to increase the detection rate and is the most reliable method of identifying vascular uptake. Failure to distinguish between procedure-related discomfort and baseline pain, as well as missing a target nerve or nerves, are other potential reasons for false-negative blocks.

Therefore, a false negative result could be the result of low concentration.

Answers

Answer:

The cell division that halved the no. of chromosomes is the meiosis. The meiosis takes place during formation of gametes (eggs & sperms) in higher organisms. eggs & sperms posses only one chromosomes of each pair of chromosomal set. (2n➡️n).

When these gametes fuse to form the zygite, the chromosomes become n+n➡️2n again.

When DNA code changes, what happens to the protein made?

Answers

This occurs when one nucleotide base is substituted for another in a DNA sequence. The change can cause the wrong amino acid to be produced. In some cases, the change has little effect. In other cases, the incorrect amino acid can affect the structure or function of the protein being encoded. A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.

The outcome of protein synthesis is ______.
A. A glucose molecule

B. An mRNA molecule

C. A protein

Answers

Answer:

C. A protein

Explanation:

The outcome of protein synthesis is a protein.

The process of protein synthesis is crucial to cellular function. Protein synthesis is the procedure used by cells to generate proteins. Thus, option C is correct.

What is the role of protein synthesis in the cell?

Protein synthesis, sometimes referred to as protein biosynthesis, is an essential biological process that occurs inside of cells to replace lost proteins (due to export or degradation) with new proteins.

Proteins have a wide range of vital biological functions, including those as enzymes, hormones, and structural proteins.

Cells are made of proteins, and the word “synthesis” simply means “to make.” Thus, the process of producing proteins is known as protein synthesis.

Creating a polypeptide, or protein consisting of a chain of amino acids, is the sole goal of protein synthesis. Keratin, a protein, is produced in the cells of the hair follicle.

Therefore, The outcome of protein synthesis is a protein.

Cellular respiration definition ?

Answers

Answer:

cellular Respiration is that cells use oxygen in mitochondria to make ATP and GTP for cells

Answer:

Cellular respiration occurs when cells utilize oxygen in their mitochondria to produce ATP and GTP.

Cellular respiration is a series of reactions that occur under aerobic conditions and result in the production of large amounts of ATP.

Explanation:

Glucose, the basic building block for starch and many sugars are one of the main sources of energy in our diet. Its oxidation can be divided into three phases in the respiration of the cells: glycolysis, the cancer cycle, and the electron transport system.

Aerobic breathing uses eukaryotes to generate energy, including all multicellular organisms and some single-cell organisms. Aerobic breathing uses oxygen – a powerful, in-kind electron acceptor.

Aerobic breathing is an extraordinarily effective process that enables eukaryotes to have complicated life and active lifestyles. It also means however that they need a continuous supply of oxygen or that they cannot get the energy to stay alive.

Other forms of respiration, which are slightly less efficient, can be used by procharian organizations such as bacteria and archaebacteria. They can therefore live in environments in which eukaryotic organisms cannot live because they do not need oxygen.

Explain what happens to an animal cell when it removed from an organism and placed into distilled water

Answers

Answer:

I think it has to do with osmosis

Explanation:

Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.

When a cell is placed into distilled water, hypertonic solution takes place.

A cell may contain many solutes so it is considered hypertonic when compared to distilled water which is hypotonic So in this case, when a cell is placed in distilled water, water moves from outside of the cell to the inside leading to swelling of the cell.

Cells created by meiosis can be
represented by which of the following?
A.2B
B.B
C.2N
D.N

Answers

Answer:

D. N

Explanation:

Meiosis is a kind of cell division which produces daughter cells that are genetically different from the parent cell and have a reduced number of chromosomes (by half).

Meiosis occurs only in reproductive cells to produce gametes. If a diploid (2n) cell undergoes meiosis, a haploid (n) daughter cell will result. This means that the chromosome number has been reduced by half in order to maintain the chromosomal number of the next generation.

As surface water in a lake cools from 4 °C to 0 °C, the water expands and becomes less dense. Why is this change in the water beneficial to the organisms living in the lake? As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms. Frozen surface water insulates the water below it, maintaining a habitat where organisms can overwinter. Cooler water is less viscous than warmer water, making it easier for organisms to move through the water. Less dense water holds more dissolved compounds, keeping water from freezing so organisms survive winter.

Answers

Answer:

As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms.

Explanation:

This change in the water is beneficial to the organisms living in the lake because the water which freezes formed spaces between water molecules, that providing microhabitats for small organisms. The cold temperature causes formation of ice crystals on the surface of water which work as an insulator whereas the lower part of the water remain warm and the organisms can survive in that environment.
