Explanation:
Many of the most important and diagnostic mammalian characteristics serve to further intelligence and sensibility, promote endothermy, or to increase the efficiency of reproduction or the securing and processing of food.
Basic structural body plan is inherited from Therapsid mammal-like reptiles.
Survival through mammalian evolution was perhaps due to their ability to move and to think more quickly than their Archosaurian counterparts.
Morphological trends were toward structural simplification:
� skull and jaw bones lost or reduced in size
� limbs and limb girdles simplified, reduced, and less laterally splayed
Fossil record provides little evidence on when endothermy actually developed.
Diagnostic or Distinguishable Characteristics of Mammals:
Soft Tissues
Skin glands: Mammalian skin contains several kinds of glands not found in other vertebrates.
Mammary Glands: Provide nourishment for the young during their postnatal period of rapid growth.

Why is exponential growth usually very rare in nature
Answer:
Explanation:
The scarcity of natural examples is due to the fact that there are population controls due to a limiting amount of resources such as food, light, shelter, water as well as to factors such as predation, climatic change, and disease.
Answer:
In the real world, with its limited resources, exponential growth cannot continue indefinitely. Exponential growth may occur in environments where there are few individuals and plentiful resources, but when the number of individuals gets large enough, resources will be depleted and the growth rate will slow down.
Explanation:
In humans, brown eyes are generally dominant over blue eyes. Find the phenotypic and genotypic ratios of a cross between two heterozygous brown-eyed people. Choose This is a required question
Answer:
Brown eyed genotype: Aa (eterofzygous) or AA (homofzygous)
The genotypes derived from the cross are: AA, Aa, Aa, aa
The phenotypes are: 3 with brown eyes and 1 with blue eyes (aa)
The phenotypic ratio is 3:1 (brown eyes: blue eyes) and the genotypic ratio is 1:2:1 (dominant homozygous: heterozygous: recessive homozygous).
What happens in a heterozygous cross?In humans, the allele for brown eyes (B) is dominant over the allele for blue eyes (b). Heterozygous individuals, who carry one copy of each allele (Bb), will have brown eyes.
When two heterozygous brown-eyed individuals (Bb) cross, the possible genotypes of their offspring are:
BB (brown eyes): 25% chance (homozygous dominant)
Bb (brown eyes): 50% chance (heterozygous)
bb (blue eyes): 25% chance (homozygous recessive)
So, the genotypic ratio of the offspring is 1:2:1 (BB:Bb:bb).
As for the phenotype, the only possible one is brown eyes and it occurs in 75% of the offspring (25% BB + 50% Bb)
Therefore, the phenotypic ratio of the offspring is 3:1 (brown eyes: blue eyes)
It's worth noting that while this is the typical outcome of crosses involving the eye color genes, it's not universally accurate, as other factors and genes might have an influence on the phenotype. Additionally, in reality, eye color is a complex trait and many other genes are involved not just B and b, so the dominance is not always that clear.

Explanation:
Photosynthesis is dependent on-
A :the nitrogen cycle
B: ammonia
C: the seasonal cycle
D: the carbon cycle
Answer:
The correct answer is - carbon cycle.
Explanation:
During the photosynthesis process, all plants consumed carbon dioxide from the atmosphere and sunlight to generate or produce glucose a biological fuel required for building structural components and produce energy. It forms the foundation of the carbon cycle.
Consumption of carbon dioxide is part of the carbon cycle. These biological fuels used in another process called cellular respiration that releases carbon dioxide into the atmosphere. Thus, the carbon cycle and photosynthesis both are interdependent.

What are four conditionsrequired for fossilizationof an organism?
Answer:
The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition. This does make the fossil record biased because animals with soft bodies are less likely to form fossils.

The colors of stained glass are metallic oxides (combinations of
different metals and oxygen), but the beautiful colors you see aren't
due solely to the coloring in the glass. It's the light passing through
the glass that reaches your eyes. The natural light changes from
morning to night, even from moment to moment. Our perception of
stained glass changes with the light.
Answer:
Yes.
Explanation:
Our perception of stained glass changes with the light because light is the main thing which allows us to see the colour of stained glass. Light has several colour but we can see them when it pass through a specific medium such as prism. The stained glass also act as a prism which allow us to see different colour when the light passes through this glass so we can say that light is responsible for the appearance of colour.

If green house emissions do not decrease, what will happen to global climate?
Predict:
Observe:
Explain:
Answer:
If green house gas emissions do not decrease the globe will increasingly get warmer. The sun's heat enters the atmosphere, some heat will escape, some will be trapped. Carbon dioxide causes the heat to remain in the atmosphere. Without carbon dioxide Earth would very cold, but with the use of fossil fuels and other unsustainable resources we are releasing too much carbon dioxide in the atmosphere. This is causes way too much heat to remain trap. And this is what is causing global warming
