1. What is an autosomal chromosome (an autosome)?​

Biology
1 answer:
Inessa [10]3 years ago
8 0

Answer:

Explanation:

An autosome is any chromosome that is not a sex chromosome (an allosome). ... The DNA in autosomes is collectively known as atDNA or auDNA. For example, humans have a diploid genome that usually contains 22 pairs of autosomes and one allosome pair (46 chromosomes total).

bulgar [2K]

Answer:

Inbreeding leaves animals susceptible to genetic disease, and populations to reduced fitness. This family of three would not be able to sustain a population given their a) group dynamics and b) genetic variation

Explanation:

In small populations, the variation in genetic material is likely to be low. The consequence of this is that there is increased homozygosity. That means less members of the population carry two different alleles of a gene for any given trait. This increases the chance of the appearance of recessive traits, which could be disease causing or otherwise reduce fitness.

With only three related individuals left, the chances of generating a new and thriving population with the limited genetic material is almost non existent, especially considering the animals are a male, female and their pup

why would having both polar and nonpolar properties in a protective boundary be advantageous for the cell?
Reika [66]

Explanation:

The polar nature of the membrane’s surface can attract polar molecules, where they can later be transported through various mechanisms. Also, the non-polar  region of the membrane allows for the movement of small non-polar molecules across the membrane’s interior, while preventing the movement of polar molecules, thus maintaining the cell’s composition of solutes and other substances by limiting their movement.

Further explanation:

Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons. Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties i.e. they are amphiphilic. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane.

How does temperature of water affect its ability to hold oxygen?
dalvyx [7]

Dissolved Oxygen and Water Temperature. The solubility of oxygen and other gases will decrease as temperature increases 9. This means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.
