Why are epithelial cells in membranes
packed tightly?
to keep organs connected
to protect organs
to form different layers
Answer:
to protect organs
Explanation:
Epithelial cells are cells found in the human skin. They are tightly packed cells which helps to protect organs in the human body.
The cells are divided into different layers with an inner part and the outermost layer.
The skin is the largest organ of the human body. It protects all organs from the external environment.

Which best compares self-renewal and differentiation?
O Both are processes that are the result of stem cell division.
O Both create more of the same types of cells.
O Both form specialized cells.
O Both depend on gene expression.
Answer:
Both are processes that are the result of stem cell division
Explanation:
Self-renewal and differentiation are the property of the stem cells. Both the processes result from stem cell division. Thus, option A is correct.
What are stem cells?Stem cells are the special cells that can produce other types of cells from differentiation. For example, the Hematopoietic Stem Cells give rise to the blood cells that can be RBC, WBC, etc.
Differentiation is the process where the less specialized cells give rise to a more specific cell type. The stem cells also undergo self-renewal where the same cell type is also produced.
Therefore, both process results from stem cell division.

You are walking in a clear-cut section of forest a few days after a heavy rainstorm A nearby stream is very muddy and has
many dead fish. What might have happened?
Answer:
in my oppinion its call a
source of pergisol
Explanation:
What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.
Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.

What are the 4 nitrogen bases in a DNA nucleotide, and how to they pair together?
Answer:
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guani

A strand of DNA contains the bases adenine, cytosine, cytosine, and guanine, in that order. Which would be the order of the bases on the opposite strand of DNA?
cytosine, adenine, adenine, and thymine
cytosine, thymine, thymine, and adenine
thymine, guanine, guanine, and cytosine
thymine, adenine, adenine, and cytosine
Answer:
thymine, guanine, guanine, and cytosine
Explanation:
The order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.
DNA and complementary base pairingThe deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

Define and give examples of greenhouse gases
Answer:
a gas that absorbs infrared radiation and radiates heat in all directions. EX) water vapor, carbon dioxide, methane, and ozone
The primary gases that cause the greenhouse effect are fluorinated gases (also known as "greenhouse gases"), water vapor, carbon dioxide, methane, nitrous oxide, and nitrous oxide (all of which are naturally occurring).
What is the effect of greenhouse gases?The so-called greenhouse effect is a result of these, low amounts of the three most well-known greenhouse gases carbon dioxide (CO₂), methane, and nitrous oxide occurring naturally in the atmosphere. Greenhouse gases on Earth trap heat in the atmosphere, warming the whole globe.
Because it is one of the gases in the atmosphere that causes the greenhouse effect, which causes the Earth to warm, carbon dioxide is known as a greenhouse gas.
Therefore, gases in the atmosphere known as greenhouse gases have an impact on the energy balance of the planet.
