Answer:

the water cycle how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.

the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.

What planets are easiest to study?

Nikolay [14]

To be honest, since we live on Earth (assuming you do as well), Earth is the easiest planet to study. We don't know much about the other planets because we've never been to any of them. I believe that the second easiest planet to study is either Uranus or Saturn.

Albinism is inherited as autosomal recessive trait. The frequency of the disease in the population equals to 1:20 000. Calculate

prisoha [69]

Answer:

0.0139- frequency of heterozygotes in the population

Explanation:

Let q to the power of 2 represents the frequency of the homozygous recessive (aa) = 1/20000 = 0.00005

This, q = √q^2 = √0.00005 = 0.007

Since p + q = 1

p = 1 - 0.007 = 0.993

Using the formula: p^2 + 2pq + q^2

Where 2pq represents the frequency of the heterozygotes, thing we have

2 x 0.007 x 0.993

= 0.0139

Which human cells never have 23 pairs of chromosomes?. . A. blood cells. . B. nerve cells. . C. mature sex cells. . D. mutant ce

Solnce55 [7]

<h3><u>Answer;</u></h3>

C. Mature sex cells

<h3><u>Explanation;</u></h3>

<u><em>Human somatic cells or body cells are diploid such that they contain two sets of 23 chromosomes which gives a total of 23 chromosomes.</em></u>
Examples <em><u>of somatic cells in the body that are diploid include, epithelial cells, somatic cells, liver cells, blood cells, nerve cells, etc.</u></em>
However, <u><em>mature sex cells are haploid, which means they have one set of 23 chromosomes which means they have 23 chromosomes.</em></u> Sex cells are the results of meiosis type of cell division in which a diploid cell divides to form four daughter cells that are haploid.

How would a cap− mutation that produces an inactive CAP protein affect transcriptional control of the lac operon? How would a mu

liq [111]

Answer:

The answer is: The lac operon transcription would be reduced.

Explanation:

The lac operon is the machinery that bacteria uses to break down lactose to use it as an energy source when there is no glucose around. The catabolite activator protein (CAP) senses glucose via a molecule called cAMP. If the levels of glucose are high then no cAMP is produced and therefore no cAMP would be able to bind CAP. That would leave CAP inactive and the transcription would occur but at low levels. The same would happen if CAP protein would have a mutation that would leave it inactive.
