Oxana [17]

Explanation:

All vital organs begin to lose some functionality as one ages during adulthood. Aging changes occur in all cells, tissues and organs of the body and affect the functioning of all body systems.

The living tissue is made up of cells. There are many different types of cells, but they all have the same basic structure. Tissues are layers of similar cells that fulfill a specific function. Different types of tissues group together to form organs.

There are four basic types of tissue:

The connective tissue supports the other tissues and joins them. This includes bone, blood and lymphatic tissue, in addition to the tissues that provide support and structure to the skin and internal organs.

The epithelial tissue provides coverage for the superficial and deeper layers of the body. The skin and lining of the ducts inside the body, such as the gastrointestinal system, are made of epithelial tissue.

Muscle tissue includes three types of tissue:

Striated muscles, such as those that move the skeleton (also called voluntary muscles)

Smooth muscles (also called involuntary muscles), such as the contents in the stomach and other internal organs

Myocardium, which makes up most of the wall of the heart (also an involuntary muscle)

Nervous tissue is composed of nerve cells (neurons) and is used to carry messages to and from different parts of the body. The brain, spinal cord and peripheral nerves are composed of nerve tissue.

Which characteristic makes osmosis different from diffusion?

nalin [4]

A) Net movement in osmosis is from areas of higher water concentration to areas of lower water concentration. Net movement in diffusion occurs from areas of higher solute concentration to areas of lower solute concentration.

This happens so that both solution have roughly the same concentration

An electron microscope would be used for if

rewona [7]

Answer:

Electron microscope would be used for if,

C) details of cell structures needed to be distinguished.

Explanation:

The general principal of electron microscopy is analogous to light microscopy except that it uses electrons to analyse the specimen instead of light.
Electron microscopy focuses a beam of electron on the target sample and records the difference in absorption by different surfaces.
Electron microscopy is used to get the detailed structure of cells and surface features of various viruses and bacteria.
However, it is not possible to view living biological samples through electron microscope because high velocity electron have immense energy to kill living cells.
These samples are thus, fixed and then viewed.

:) please help!!! Briefly describe the traits seen in each genotype:

kolezko [41]

<h2>Answer 1 with Explanation</h2>

Homozygous dominant- It can be an organism if it carries two copies of the same dominant allele as homozygous which clearly means that the organism has a pair of models that is the corresponding allele for a gene. This gene originally belongs to a particular gene that has same alleles on both homologous chromosomes. It is assigned to by capital (XX) in the subjective terminology.

<h2>Answer 2 with Explanation</h2>

Heterozygous dominant is an organism that carries two different alleles of a gene. Though this is originally is referred to as (Tt). Heterozygous means that an organism has two different varieties of the gene within the system of dominant, the protein each makes is slightly different from one another and the organism has both tall and short versions within the dominant.

<h2>Answer 3 with Explanation</h2>

Homozygous recessive is described as an organism that carries two copies of the same recessive allele in the living organisms while they are in process of growth. A recessive gene is one that has to be homozygous to have an effect on the plant's or animal's traits that is naturally in process. This process of homozygous is is referred to by the lower case (xx).
