Answer:
Tissue is a group of cells that have similar structure and that function together as a unit. primary types of body tissues include epithelial, connective, muscular and nervous tissues. Epithelial tissues form the covering of all body surfaces , ine body, cavities and hollow organs, and are the major tissues in glands.
A tissue is composed of a group of cells that are determined to play a specific function. The Cytoplasm is a dense gel-like material that is filled within the cell.
What is Cell theory?Cell theory was proposed by M. Schleiden and T. Schwann in 1838. According to them, there are three postulates of cell theory that are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.The cell is the structural and functional unit of life.Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells. The Cell wall generally protects the cell and it is most commonly found in plants, animals, bacteria, etc.
Inside the cell, there are various organelles present that perform specific functions for the survival of the cells. The nucleus is known as the brain or controlling center of the cell, which transmits genetic information from one generation to the next.
Therefore, each of the above-given term is justified above.

There are several buffer systems involved in maintaining blood pH, but one is more important than the others for maintaining acid-base homeostasis in blood. To understand why an acid-base imbalance in the blood results from respiratory depression, you must first identify the major buffer system responsible for controlling blood pH. Which equilibrium reaction is the most important for maintaining acid-base homeostasis in the blood?
Answer:
The Carbonic-Acid-Bicarbonate Buffer. In animals with lungs, the carbon / bicarbonate buffer system is especially effective. In these animals, the H2CO3 in the blood plasma is in equilibrium with the gaseous CO2 present in the airspace of the lungs, which represents a practically unlimited reserve of CO2 that can participate in the equilibrium.
Explanation:
In the Carbonic-Acid-Bicarbonate buffer system, 3 reversible equilibria take place between the CO2 gas in the lungs and the bicarbonate dissolved in the blood. The bicarbonate ion (HCO3-) can combine with a proton (H +) to form carbonic acid (H2CO3), thus absorbing protons from solution and raising blood pH. Carbonic acid, which can be formed from CO2 and water, can dissociate into H + and HCO3- to provide H + and lower blood pH. Carbonic acid, which can be formed from bicarbonate, is converted to CO2 and water by a very fast enzymatic reaction. CO2, being volatile, can be rapidly eliminated from the body in variable amounts through respiration.In the clinic, the system that is measured for the assessment of the acid-base status is the carbonic / bicarbonate system.

A cleft chin in humans is coded by the dominant allele C. A chin without a cleft is coded by the recessive allele c. A man with a cc allele combination for the trait produces a zygote with a woman with a Cc allele combination for the trait. Which allele combinations could occur in the zygote?
Answer:
The allele combinations are: Cc, cc, Cc, cc
Phenotypically there is a 50% chance that the child will be born with or without the cleft
The allele combinations that could occur in the zygote is Cc or cc.
What is an allele combination?An identification of the specific alleles found at each of the relevant mouse loci on the two homologous chromosomes (i.e., all allele pairs of a genotype). One or more allele pairs can make up an allele combination.
Genetic linkage is the capacity of a chromosome to transmit alleles that are near to one another as a whole unit through meiosis. Inheritance of traits is also understood by this principle. It is useful in locating the genes that are in charge of characteristics and diseases.
The person is homozygous for the allele if the two alleles are the same. The person is heterozygous if the alleles are different.
Therefore, the zygote may include the allele combinations Cc or cc.

Answer:
the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.
Differences:
- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from
- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases
- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors
Explanation:
Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:
1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.
2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)
3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.

Snowshoe hares have large hind feet that prevent them from sinking into soft snow. Their brown coats turn white in the winter to blend in with the snow. These hares have adapted in order to survive and reproduce in their snowy environment. What is this an example of?
A. fitness
B. overproduction
C. variation
D. competition
Answer:
A. fitness
Explanation:
Fitness, also known as 'evolutionary fitness', refers to the ability of one species/population/individual to survive and reproduce in its environment. Fitness is a fundamental concept in the evolutionary theory proposed by Darwin, because this concept highlights the importance of natural selection as the key mechanism by which evolution occurs. Fitness can be measured as the success of passing genes associated with specific phenotypic traits to the next generation.
The skin cells of an organism are analyzed and cells identified in G1 and have an average of 12 picograms of DNA. In the same organism a cell from gonadal tissues is identified and that single cell contains 6 picograms of DNA. Given this information, which of the following is true about the single gonadal tissue cell with 6pg of DNA?
1. The cell is at the beginning of Prophase I.
2. The cell has already completed meiosis.
3. The cell is not dividing (is in interphase).
4. The cell contains unduplicated chromosomes.
Answer:
El Rasho Macuin
Explanation:
The statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis. So, the correct option is B.
What do you mean by DNA?It is a complex molecule that contains all the information necessary to build and maintain an organism. It stands for Deoxyribonucleic acid. It is considered the genetic material in most organisms.
The skin cells in the G1 phase have an average of 12 picograms of DNA. As the amount of DNA in the G1 phase is 2C, hence 2C = 12 pg of DNA.
Now in the same organism, a cell from gonadal tissue is identified and that single cell contains 6 pg of DNA, which means, the amount of DNA is 6 pg that is C. Therefore, after the completion of meiosis, the cell contains half the amount of DNA as compared to the parent cell in G1.
So, Amount of DNA = C = 6 pg.
Therefore, the statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis.
