Clearly your only giving 5 points but ok.

Answer:     Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

Buy less plastic and bring a reusable shopping bag. Use long-lasting light bulbs. Energy efficient light bulbs reduce greenhouse gas emissions. Also flip the light switch off when you leave the room!

The human infant spends about half of its sleep time in rem. What is the understanding of why this is the case?
Molodets [167]

This occurs because REM sleep may provide at least part of the stimulation necessary to correctly develope the immature brain of infants.

REM sleep provides the electrical activity necessary to establish neural connections that include the  development of synapses in the brain. These neurological process enables development of sensory, motor, learning and memory system.

The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability
Zinaida [17]

Answer:

Explanation:

<em>Let the ability to break down the red color in beets be represented by the allele </em><em>B</em><em>. The inability would be represented by the allele </em><em>b</em><em>.</em>

A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.

A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:

            <em>Bb     x     Bb</em>

<em>            BB    2Bb    bb</em>

1.

(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.

Probability of having a girl = 1/2

Probability of being a secretor = 1/4

<em>probability of their first child will be a secretor girl</em> = 1/2 x 1/4 = 1/8

(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.

Probability of having a girl = 1/2

Probability of being a nonsecretor = 3/4

<em>Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor</em> = 1/2 x 3/4 = 3/8

2. <em>Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.</em>

  = 3/4 x 3/4 = 9/16

Ovules produced by an entirely green plant contain a rare mutation in a nuclear gene that is involved in chlorophyll synthesis,
sveticcg [70]

Answer:

The plant will produce less chlorophyll

Explanation:

The plant still has a functional allele provided by the paternal gamete, thereby the leaves have this enzyme required for chlorophyll biosynthesis. In consequence, the plant can produce chlorophyll pigment but in less quantity, since it has only a functional allele coding for a key enzyme involved in the chlorophyll pathway

A scientist performs an experiment in which they create an artificial cell with a selectively permeable membrane through which o
Alborosie

Answer:A. Water moves into the cell

Explanation:water moves into the cell through osmosis.during osmosis water moves from a region of low concentration of solute to a region of high concentration of solute.the glucose introduced into the cell makes it more concentrated.

In this case the cell is hypertonic and water would enter into the cell through the semi permeable membrane.this membrane allows water to pass through but not glucose.this movement of water into the cell causes the cell to become turgid.
