Can animals see in the dark better than humans?

Answers

Yes. Because their eyes give light they do. Just joking. Eyes reflecting is from other light sources. But they do have better night vision. Most of nocturnal animals have bigger eyes or pupils, which make it easier to catch up environmental light.

I believe it is the Nitrogen cycle although all of the cycles use bacteria. Only nitrogen requires nitrogen fixing bacteria to keep the cycle going.

Which organelle can be compared to a security guard who decides whom may enter a building and whom may not?

Answers

The answer is the cell membrane. The cell membrane controls what nutrients come in, and what unneeded material comes out. It protects the cell from anything that might come in and harm it. It is kind of like the security guard. A security guard let's the good people in and keeps the bad people out.

Final answer:

The cell membrane is comparable to a security guard. It regulates the substances that enter and exit cells, allowing necessary substances in and keeping harmful ones out.

Explanation:

The organelle that can be compared to a security guard who determines who is allowed to enter and exit a building is the cell membrane. The cell membrane, also known as the plasma membrane, is a biological structure that separates the interior of cells from the outside environment. It functions similarly to a security gatekeeper, regulating the transport of substances in and out of cells. For example, it allows useful substances such as glucose and amino acids to enter the cell while preventing harmful substances from entering. In this way, the cell membrane ensures the safety and functionality of the cell, acting as its security guard.

Mr. Potter’s physical science classes conducted an experiment to determine the density of aluminum. Here are the density values each class period came up with: 1st hour = 3.1 g/ml, 2nd hour = 3.05 g/ml, 3rd hour = 1.9 g/ml, 4th hour = 2.35 g/ml, 5th hour = 4.2 g/ml, and 6th hour = 4.0 g/ml. If Aluminum’s true density is 2.7 g/ml, how would you group the class values based on accuracy?a.

Group: 1st, 3rd, 5th, and 6th hours, with one recorded decimal place in their values

Group: 2nd and 4th hours, with two recorded decimal places in their values

b.

Group: 3rd and 4th hours, with values under the true density

Group: 1st, 2nd, 5th, and 6th hours, with values over the true density

c.

Group: 3rd hour, with a 1 value

Group: 4th hour, with a 2 value

Group: 1st and 2nd hours, with 3 values

Group: 5th and 6th hours, with 4 values

d.

Group all classes as accurate

Answers

Answer;

B. Group: 3rd and 4th hours, with values under the true density. Group: 1st, 2nd, 5th, and 6th hours, with values over the true density.

Explanation;

Accuracy refers to the closeness of a measured value to a standard or known value.

Accuracy is a qualitative term referring to whether there is agreement between a measurement made on an object and its true (target or reference) value.

B. Group: 3rd and 4th hours, with values under the true density
Group: 1st, 2nd, 5th, and 6th hours, with values over the true density

What aligns and segregates during meiosis I? What aligns and segregates during meiosis II? In what way is prophase I of meiosis similar to prophase of mitosis? How is it different? In what way is metaphase I of meiosis similar to metaphase in mitosis? How is it different? Which is more similar to mitosis (meiosis l or meiosis II)? What is the important similarity? What is the significance of meiosis in terms of the genetic content of the cells produced? In terms of the genetic makeup of the whole species? What are two features of meiosis that result in the production of genetically distinct gametes?

Answers

What is the significance of meiosis in terms of the genetic content of the cells produced?

Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer).

Answer:

begin with a single parent cell which eventually splits to form new daughter cells.
