3)What are some examples of specialized cells
and what do they do?
4) Why is the specialization of cells in organisms
significant and important for homeostasis?

Answers

Answer:

3 Neurons are the specialized cells responsible for allowing all the basic body functions to take place correctly as all the necessary communication happens through them. Muscle cells or myocyte cells are specialized in making all movement possible. These cells have a cylindrical shape that allows them to contract.

Explanation:

4 Each cell must be able to perform as a part of a living organism. Cell specialization is required for cells to perform as a part of a whole living thing. Different cells do different jobs.

Which of the following explains how rumen biotechnology improves feed for ruminant animals?
by identifying small amounts of bacteria from tiny samples of meat
by boosting the bioavailability of carbohydrates and protein in plants
O by helping animals grow larger more quickly and produce cleaner meat
O by screening animals for physical defects and certain diseases

Answers

Rumen biotechnology improves feed for ruminant animals by boosting the bioavailability of carbohydrates and protein in plants. It can be used to improve the nutritive value of ruminant feedstuffs.

Rumen biotechnology refers to the use and management of the techniques of forestomach fermentation in order to improve the efficiency of ruminant production.

Rumen biotechnology can be used to improve the amount as well as the availability of macronutrients (i.e., carbohydrates and proteins) in plants.

However, this technology (rumen biotechnology) exhibits several limitations mainly associated with the identification of bacterial strains used during inoculation, proteins (recombinant enzymes) and genomic stability of the genetic constructs.

There are no ____________ in the ____________ , located where the nerve fibers of the ____________ leave the eye and enter the ____________ . Consequently, this region of the retina is commonly called the ____________

Answers

There are no PHOTORECEPTORS in the OPTIC DISC located where the nerve fibers of the RETINA leave the eye and enter the OPTIC NERVE. This region is commonly called the BLIND SPOT.

The retina is an important layer of nervous tissue that covers the inside of the eye, in which the sensation of vision initiates.

Photoreceptors are specialized cells within the retina that respond to light stimuli. In the retina, there are two types of photoreceptor cells: cones and rods.

The blind spot is a small portion of the visual field of the eye that localizes in the optic disk within the retina.

There are no rods or cones (i.e. photoreceptor cells) within the optic disk.

A student named Janine says that the measure of side b is 64 ft. Please state whether this is correct or incorrect. If this is incorrect, state the length of b. Explain your answer in complete sentences. Use vocabulary such as Pythagorean Theorem, side, hypotenuse, square root etc.

Answers

The measure of side b as 64 ft is incorrect. The accurate measure would be 8 ft.

According to the Pythagorean theorem, the square of the hypotenuse of a right-angle triangle is the sum of squares of the opposite and the adjacent sides. Mathematically:

[tex]hypotenuse^2 = opposite^2 + adjacent^2[/tex]

In this case, the hypotenuse = 10 ft, the opposite = 6 ft and the adjacent = b

Hence,

b^2 = 10^2 - 6^2

       = 100 - 36

          = 64

b = √64

     = 8 ft

Thus, the side b is 8 ft and not 64 ft.

Say that you look at the nuclei of 100 skin cells taken from the same person. About how many of these skin cells would you expect to be in interphase

Answers

Answer:

45 cells would be in the interphase

In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.

What are cells?

Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.

Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.

Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.

Therefore, the number of skin cells in the interphase is 45 cells.

As wind passes over a mountain, the side over which the wind rises tends to be ____________________ and the side that experiences the downward movement of air tends to be ____________________.

drier; moist and rainy

moist and rainy; drier

rainforest; desert

desert; rainforest

Answers

Given what we know about the effects of air currents on mountain ranges we can confirm that the correct option is option B, moist and rainy on one side while being dier on the other.

Mountains are described as having two sides in regards to their relationship with the air currents. The side of the mountain on which the wind rises is known as the windward side, whilst the side on which air descends is known as the leeward side. The windward side is typically in contact with warmer, moist air from the ocean and other bodies of water.

When coming in contact with the mountain, the air is forced to rise and begins to cool, which often leads to rain or snow. The leeward side of the mountain receives the air that has now already lost the majority of its moisture with its pass through the windward side of the mountain. This air also tends to become warmer as it descends, which explains the dry nature of the leeward side of mountains.
