the rusty crayfish is harmful to Native species of crayfish because it clear cut the bottom of waterways leaving native species without a food supply

T or F

Answers

I think its true hope this helps.

Answer: True

Explanation:

An invasive species is the one which competes with the members of the native species for resources when introduced to a new ecosystem.

According to the given situation, a rusty crayfish is harmful to the native species of crayfish. This tells us that rusty crayfish is invasive for native species of crayfish. Thus the native species left without food as there exists competition for food.

In the cells of some organisms, mitosis occurs without cytokinesis. this results in ________.
a. cell cycles lacking an s phase
b. cells lacking nuclei
c. cells that are unusually small
d. cells with more than one nucleus

Answers

In the cells of some organisms, mitosis occurs without cytokinesis. this results in THE CELLs WITH MORE THAN ONE NUCLEUS. After the DNA duplication in the cell, mitosis occurs during which two chromosome sets are separated by the formation of two nuclei. Lack of mitosis would lead to lack of cytokinesis ie., cytoplasm and nuclei will not e divided and would be present in a single cell itself.
Final answer:

When mitosis occurs without cytokinesis, it leads to cells with more than one nucleus. This results from the genetic material being divided without the subsequent division of the cell's cytoplasm, possibly leading to larger, abnormal cells that can be indicative of cancer.

Explanation:

In the cells of some organisms, when mitosis occurs without cytokinesis, the resulting condition is cells with more than one nucleus. This happens because the cell divides its genetic material during mitosis but fails to complete the process by not undergoing cytokinesis, which is the division of cytoplasm to form two separate cells. This cell cycle aberration can lead to larger cells containing multiple nuclei, which is often an unwanted phenomenon that could indicate the presence of cancerous cells.

Cell cycle control is crucial for an organism's health as it ensures that cells divide correctly and maintain proper function. If this control is lost, cells may begin to divide uncontrollably, which is a characteristic of cancer, leading to the formation of tumors.

The cell cycle has two major phases: interphase, where the cell grows and the DNA is replicated, and the mitotic phase, where the cell actually divides. The mitotic phase includes karyokinesis (the division of the cell's nucleus) and usually cytokinesis. However, when cytokinesis does not occur, the result is a multinucleate cell, which has replicated DNA and might be larger in size but hasn't physically separated into two individual daughter cells.

Which enzyme is responsible for the majority of the digestions of lipids?

Answers

The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.

Pancreatic lipase is the primary enzyme responsible for lipid digestion, working mainly in the small intestine to break down triglycerides into fatty acids and monoglycerides.

The enzyme responsible for the majority of the digestion of lipids is pancreatic lipase. It operates primarily in the small intestine, where it systematically breaks down each triglyceride molecule into two free fatty acids and a monoglyceride. This process is facilitated by bile, which is secreted by the liver and works to emulsify large globules of food lipids into smaller micelles, providing a larger surface area for the pancreatic lipase to act upon. Lipid digestion begins to some extent in the mouth with lingual lipase, but this is minor in comparison to the activity in the small intestine.

which of the following is part of the cell theory

All cells are produced from other cells
All cells are the same.
cells are independent structures
Cells are able to make new organisms.

Answers

A. All cells are produced by other cells, and this is a confirmed answer, no worries

The part of the cell theory among the given options is All cells are produced from other cells.

The correct option is A

The cell theory is a fundamental principle in biology that describes the basic properties and functions of cells. It consists of three main principles: All living organisms are composed of one or more cells.

The cell is the basic unit of structure and function in living organisms.

All cells arise from pre-existing cells through cell division. The statement "All cells are produced from other cells" aligns with the third principle of the cell theory. It emphasizes that new cells are generated through the process of cell division, where existing cells divide to produce daughter cells. This principle applies to all forms of cellular life and is a cornerstone of our understanding of cellular reproduction and the continuity of life.

Hence , B is the correct option

If a baby boy inherits a recessive allele from his mother, in which of the following circumstances would he most likely exhibit that recessive trait? (2 points)

a.The allele is X-linked.

b.His mother's father also exhibited the trait.

c.The allele skips a generation.

d.He inherited the dominant trait from his father.

Answers

a.The allele is X-linked

Women have two X chromosomes while men have one X and one Y.
In the case of a recessive mutation on the X chromosome passes from the mother to the baby boy, the boy will express the recessive allele. Even though it's recessive, and in allosomes both alleles need to be present, when it comes to this situation the boy only has one X chromosome so it's indifferent if the gene is recessive or dominant.

The allele us X-linked

Long, saturated fatty acid tails _____ lipid mobility and _____ membrane fluidity. enhance; increase reduce; increase enhance; maintain maintain; decrease reduce; decrease

Answers

reduce lipid mobility
decrease membrane fluidity

When fatty acid tails are saturated, it means that their conformation is perfectly straight becoming easy to compact more and more fatty acids, as they fit perfectly together, and therefore reducing lipid mobility. In turn, if lipid mobility is reduced, the membrane fluidity is decreased because the lipids are too "stiff" together.
