Why are groups of small cells better than one large cell at moving material in

Biology
1 answer:
kirill [66]2 years ago
7 0

The groups of small cells better than one large cell at moving material in  and out because they have a greater surface-to-volume ratio.

<u>Option: A</u>

<u>Explanation:</u>

This happened so as these smaller cells, unlike bigger cells, can quickly and willingly enter and move through the membranes of other cell membranes and permeable coverings. For these smaller and mini cells, it is also important to penetrate and move effectively, distribute and transport products and materials such as nutrients, oxygen and waste across the body without requiring enough energy and saving less space. They are cheaper, more effective and use less room for simple reasons, and most notably deplete less resources.

According to the diagram below, what type of organism converts atmospheric nitrogen (N2) to ammonia (NH3) and then to nitrites (
Nookie1986 [14]

Answer: Nitrogen-fixing Bacteria

Explanation:

In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.

Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.

A woman who is colorblind (XcXc) can expect - Select one: a. 100% of her female offspring to be colorblind b. 100% of her male o
8_murik_8 [283]

Assuming she reproduces with someone who doesn't have the color blind gene:

XcXc * XCY

There are 4 combinations

XcXC

XcXC

XcY

XcY

As both of the males have the Xc gene, she can expect 100% of her male offspring to be colorblind.

What two types of amino acid sequences are needed in a protein to mediate post-translational farnesylation?
Hitman42 [59]

Answer:

Post translation farnesylation may be defined as a type of prenylation in which the isoprenyl group is added to the cysteine residues of the protein. This modification is important for protein and membrane interaction.

Basically two types of amino acid are required for the farsenylation modification. The signal peptide sequence is the short amino acid sequence that targets the ribosome in the endoplasmic reticulum. The sequence is generally lysine, aspartic acid, glutamic acid and leucine. The second sequence must be Caax (C is cysteine, a is aliphatic amino acid and X consists of C terminal amino acid.
