Anton Van Leeuwenhoek first person to observe a living cell in a drop of pond water.

Explanation:

In the year 1830 THEODOR SCHWANN and MATTHIAS SCHLEIDEN explain the developments of the cell theory based on the study they have done on the living tissue. This theory explains that all living tissues are made up of a cell, the basic unit of life is cell and all new cells arise from the preexisting cell,and Rudolf Virchow he also made some important contributions to the cell theory.

In the year 1665, Robert Hooke observed cork with the help of lens, and he observed that the cork is made of compartments, are connected to each other. He named the word as cell, to the structure he has observed in the cork.

Anton Van Leeuwenhoek he used to study the living organisms present in the rainwater, pounds and well water, then in the year 1674 the first time he observed protozoa and after that bacteria.

Answer:

False

Explanation:

All bacteria  contain peptidoglycan in the their cell wall; the major component of peptidoglycan is the N-acetylmuramic acid. The peptidoglycan in bacteria helps to protect the bacteria plasma membrane and cell as a whole from environmental stress as well as maintaining its cell morphology.

In this case, the unicellular organism that was discovered is most likely an archaea. Archaea are organisms that have a semi rigid cell wall with the absence of peptidoglycan.

What negative effect does sickle-cell disease have on the circulatory system?
Tatiana [17]

Answer:

Because sickled cells restrict blood flow, individuals can periodically experience swelling and extreme pain in any body organ or joint. This can last for hours or weeks. Sometimes permanent damage can occur to organs deprived of oxygen and nutrients

Explanation:

Red blood cells are designed to pick up oxygen in the lungs and transport it throughout the body via the circulatory system. Their donut-like shape and water-balloon-like flexibility allows them to pass through even the tiniest blood vessels.

Sickle cell anemia is a hereditary condition that causes some red blood cells to distort into rigid crescent moon shapes.

Normal red blood cells can flow freely through blood vessels. Sickled cells get stuck in the blood vessels and cause blockages.

Which factors are most significant in describing the climate of a region
bezimeni [28]
<span>Climate describes the average conditions and atmospheric patterns of a region over time. In describing the climate of a region one may specifically include precipitation, humidity, temperature, sunshine, wind velocity, fog, frost, and hail storms that have been observed for a long period of time. 

The average weather statistics for determining a region's climate is in a span of 30 years. Scientists must make observations within a specified interval to determine the climate of a particular location. </span>

How many chromosome would be found in dog gametes?
mezya [45]
In dog gametes, there are half the chromosomes contained in normal diploid cells. In the normal diploid cell of the dog there are 78 chromosomes, thus, in dog gametes, there are 39 chromosomes.
Similarly, in deer mouse brain cells there are 48 chromosomes since brain cells are diploid cells.
In gametes there are half of that number, so in deer mouse gametes there are 24 chromosomes.
