A typical human karyotype has 23 types of chromosomes arranged from largest to smallest. In males and females 22 of these chromosomes look exactly the same and they are called autosomes. The 23rd pair of chromosomes is the sex chromosome which differentiates males from females. Females have 2 copies of the x chromosome. Males have a copy of both x and y chromosome to make the 23rd pair. <span>

<span>Chromosomes can also have abnormalities that result to different conditions and identifiable traits. A most common chromosomal abnormality is the condition called Down Syndrome, where chromosome 21 has a third copy because of an abnormal cell division.</span></span>

Paragraph<br> 2. In an atomic model, what particles are found inside the nucleus of an atom?
Vitek1552 [10]

Answer:

The protons and the neutrons are found in the nucleus of an atom.

Explanation:

Atoms are best described as the smallest unit of any matter.

Protons can be described as part of an atom which carries a positive charge. The protons are enclosed in the nucleus of the atom.

The neutron is the part of the atom that carries zero charge. The neutron is also enclosed in the nucleus of the atom.

The electrons can be described as the part of an atom that carries a negative charge. The electrons move around the nucleus in orbits.

A scientist is comparing the outer structure of an onion cell, structure X, to the outer structure of a human skin cell, structu
hammer [34]

Answer:

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  

Explanation:

The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.

Structure X is not living, and structure Y is living.  - this is false, both animal and plant cells are living.

Structure X can be found in some human cells, and structure Y can be found in some plant cells.  - this is false, the opposite is true.

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  - this is true structure X is the plant cell wall, and structure Y is the cell membrane

Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.

Alcohol dehydrogenase (ADH) is an enzyme that aids in the decomposition of ethyl alcohol (CH3OH) into nontoxic substances. Methy
Thepotemich [5.8K]

Answer:

d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.

Explanation:

Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.

Their active sites are primary protein  3D structure  for binding with substrates during   reactions.

Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,

This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites  occupied, therefore denying the inhibitor methylalchol  chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites

Which is a result of a seasonal change (meaning a change that happens over
weqwewe [10]

Answer:

A. Chipmunks sleeping underground through the winter

Explanation:

A seasonal change in the behavior of a living organism is a change that occurs every year at a particular time. The reasons for the occurrence of such changes are so that the organism has advantage in survival in the environment. In this case we have the chipmunk that sleeps underground through the winter. We have an animal which exhibit a seasonal change every year, during the winter period. The reason for this is that the chipmunks have very quick metabolism, so if they are active during the winter they will starve because of lack of food. Instead, the chipmunks have evolved to hibernate during the winter, thus slowing down the work of their hurt during the winter and sleep, until the spring comes.
