Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Numerous cell cycle regulatory components, including cyclins, cyclin-dependent kinases (Cdks), and cyclin-dependent kinase inhibitors, regulate the cell cycle (CKIs).
What is a factor that controls cell division?Positive cell cycle regulators cyclins and Cdks activate cell cycle components that are necessary for the beginning of the subsequent cell cycle phase.
The Influences on Cell Division Nutrients. Genetics: The nutrients in the cell have an impact on cell division. Cell division is controlled by genetic code and chemicals. Cell mutation can occur as a result of exposure to hazardous substances like pesticides and some cleaning products. Stress. Cell division is impacted by stress.
Therefore, numerous cell cycle regulatory components, including cyclins, and cyclin-dependent kinases Cdks.

Oxygen is carried through the blood by the protein hemoglobin. It is said in the article that a mutation of this protein known as
is the result of oxygen poor blood, which appears blue in veins.
A)Hemotosin
B)Methemeglobin
C)Hemolethoglobin
D)Blood Platelets
Answer:
The correct answer is - B) Methemeglobin.
Explanation:
Methemeglobin is a blood disorder due to the mutation in the hemoglobin which is known as the result of oxygen-less blood. In this disorder, the tissue did not get enough oxygen and appeared to be purple, or blue.
In this mutated form of hemoglobin iron atoms present in ferric instead of the ferrous state and therefore not able to bind with oxygen. It appears blue in veins and tissues look blue or purple.

Answer:
Wind- A
Sunlight- A
Deer- B
Soil- A
Sunflower- B
Water- A
Fungus- B
Snow- A
Eagle- B
Temperature- A
Explanation:
In an ecosystem and biology as a subject, environmental factors are either biotic or abiotic. BIOTIC FACTORS are those factors that involves living organisms i.e. factors that have life in them. For example, the biotic factors denoted as 'B' in this question are deer, sunflower, fungus, eagle which are all under plant, animal or microbes category.
On the other hand, ABIOTIC FACTORS are factors that involve non-living or inanimate objects i.e. factors that have no life in them. For example, the abiotic factors denoted as 'A' in this question are wind, sunlight, soil, water, snow, temperature etc.

B) the WWI discovery of paleomagnetic reversals
C) the 1963 mapping of the tectonic plate boundaries
D)C-14 dating of marine fossils found in the himalayas

In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true-breeding. If plants with blue flowers are crossed to red-flowered plants, all F1 plants have yellow flowers. When these produced an F2 generation, the following ratio was observed: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve. Determine the F1 results of a cross between true-breeding red and true-breeding mauve flowered plants.
Answer:
F1) 100% bbRr, red flowered plants.
Explanation:
Available data:
flowers may be yellow, blue, red, or mauvecolors may be true-breedingthe cross of blue-flowered plants with red-flowered plants, produce plants that have yellow flowersF2 generation: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve.Knowing that the phenotypic ratio is 9:3:3:1, we can assume that there are two genes involved in the flower color expression. We can name these genes B and R with a dominant and a recessive allele each (B, b and R, r respectively).
According to the first cross, we might establish the following genotypes:
1st Cross: blue-flowered plant x red-flowered plant
Parentals) BBrr x bbRR
Gametes) Br, Br, Br, Br bR, bR, bR, bR
F1) 100% BbRr, yellow plants
Parentals) BbRr x BbRr
Gametes) BR, Br, bR, br
BR, Br, bR, br
Punnett square) BR Br bR br
BR BBRR BBRr BbRR BbRr
Br BBRr BBrr BbRr Bbrr
bR BbRR BbRr bbRR bbRr
br BbRr Bbrr bbRr bbrr
F2) 9/16 yellow ---> 1/16 BBRR + 2/16 BBRr + 4/16 BbRr + 2/16 BbRR
3/16 blue ------> 1/16 BBrr + 2/16 Bbrr
3/16 red---------> 1/16 bbRR + 2/16 bbRr
1/16 mauve ----> 1/16 bbrr
So,
Yellow-flowered plants: BBRR, BBRr, BbRR, BbRrRed-flowered plants: bbRR, bbRrBlue-flowered plants: BBrr, BbrrMauve-flowered plants: bbrrAccording to these genotypes, the second cross would be like following,
2nd Cross: true-breeding red-flowered plants with true-breeding mauve flowered plants.
Parentals) bbRR x bbrr
Phenotype) Red Mauve
Gametes) bR, bR, bR, bR br, br, br, br
Punnett square) bR bR bR bR
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
F1) 100% bbRr, red flowered plants.

The granite boulders in Rocky Mountain National Park are a favored place among talented climbers who specialize in the art of bouldering, or climbing harder (but shorter) routes without tying into a rope. Climbers have taken to (illegally) stashing foam crash pads underneath the boulders but marmots and other rodents chew up the pads and the litter is spread by the wind. Why would the park be overused in this manner
Answer:
Follows are the solution to this question:
Explanation:
The National Park for Rocky Mountain is among the nation's best popular national parks. Rich fauna wandering the valley and also some derisive recreational sports on the planet including its majestic peaks throughout every way is no surprise that each year upwards of 3.5 million people flocks to this park. Throughout this issue, the park would be overplayed as described, since the marginal private expense of using the parks is less than those of using the park at a marginal cost.

Why is absolute dating more accurate than relative dating?
Answer:
Absolute dating is a technique that uses radioactive minerals present in rocks and fossils while relative dating compare the sample in terms of age difference. However, absolute dating is more accurate because it uses half-life of an element and provides dates in years.

How are photosynthesis and cellular respiration related?
A. The products of photosynthesis are the reactants of cellular
respiration
B. Cellular respiration is the process animals use to produce glucose,
while photosynthesis is the process plants use to produce
glucose.
C. Photosynthesis produces water molecules, while cellular
respiration splits water molecules apart.
D. Cellular respiration provides the energy for photosynthesis.
Answer:
I would say your answer for this question would be Option D: Cellular respiration provides the energy for photosynthesis.
Explanation:
Photosynthesis is the process by which plants use the energy from sunlight, carbon dioxide, and water and convert them into food, and Cellular resipration is the process by which organisms use oxygen to break down glucose and convert it to usable energy. That means that Option B can be crossed out, along with Option C. In Option A, the products of photosynthesis are not the reactants of cellular respiration, but rather the user of the energy that Cellular respiration provides. That means you can cross out Option A, and now you are left with Option D as your answer.
Answer:
A. The products of photosynthesis are the reactans of cellular respiration

What type of volcano forms mostly near hotspots?
1. Shield
2. Composite
3. Cinder Cone
Answer:
shield volcanoes
