Answer:
Explanation:
In addition to playing this structural role, the cytoskeleton is responsible for cell movements. These include not only the movements of entire cells, but also the internal transport of organelles and other structures (such as mitotic chromosomes) through the cytoplasm

levels of fitness die?
How do adaptations help an organism as they struggle for existence?
Answer:
low level of fitness means the individuals have little or no adaptations.
while adaptations are those changes that help an organism to struggle and survive. it increases the survival rate of an organism. adaptations are the changes in DNA in the form of mutations and recombinations. it increase immunity of an organism and improve its fitness.

Which 2 events during meiosis increase GENETIC
VARIATION by ensuring that each egg and each
sperm will be unique?
Answer:
(three) crossing over, mutations caused during crossing over, and independent assortment.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.

Why do we use different radioactive isotopes to determine timescale?
We use different radioactive isotopes to determine timescale because decay within the rocks according to their half-life rates, and by selecting the appropriate minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.

Answer:
co2 and c6h12o6
Explanation: 6CO2 + 6H2O → C6H12O6 + 6O2 is the photosynthesis reaction and respiration is the reverse
How can an organism's environment affect its traits?
First, I read that so incorrectly. Awkward.
An organism's environment affects its physical and self traits by making them adapt. Charles Darwin had discovered this theory with the finches. Places that were harder to get food would make these finches physical change over evolution to help them survive. It changes the animals habits depending on their resources. If a bird eats berries but there is no berries then the bird will have to change its diet or it will die.

Does a mom or dad ever give more DNA to a baby than the other parent? Why?
The mother actually gives more DNA to a baby more than the father because of the little organelles, aka the mitochondria that live inside your cells are only to be received from your mother.
But in DNA, it can vary who's side you can get more of, and in some rare cases, equally. This is because dominant genes carry out around 75% of the time and genes that are recessive can carry out 25% of the time, depending on the genetics of both the mother and the father. Example, brown eyes are a dominant gene over blue eyes, so there is a 75% chance that the baby will have brown eyes and a 25% chance that the baby has blue eyes if one parent has the brown eye gene and one has the blue eye gene.

C. It is more than 2.1 million years old.
D. It is exactly 1.4 million years old.
Answer:
B
Explanation:
It is less than 1.4 million years old
Based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.
What do you mean by Fossils?Fossils may be defined as the dead and organic remains of the past organisms which are preserved deep in the soil over a long period ago.
The fossil found in area A is very recent from the evolution point of view. The deeper the layer, the oldest is the fossil.
Area A of the fossil is synthesized after the time period of 1.4 million years ago, hence the fossil present in that area would be less than 1.4 million years old.
Therefore, based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.

True or false: the tail portion of phospholipid molecule is hydrophobic
Answer:
true
Explanation:
The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic. Since the tails are hydrophobic, they face the inside, away from the water and meet in the inner region of the membrane.
The statement "the tail portion of the phospholipid molecule is hydrophobic" is definitely true.
What is Phospholipid?Phospholipid may be defined as an amphipathic molecule that is constructed from four components. They are fatty acid, a platform to which fatty acids are attached, a phosphate, and an alcohol attached to the phosphate.
The molecule of phospholipid has a polar head and a non-polar tail. The polar head is known as hydrophilic and a non-polar tail is known as hydrophobic.
Such types of tails move away with water, hence they are significantly found at the inner side of the membrane and form a type of barrier.
These tails of phospholipids are typically uncharged which expel water and separates the internal contents of the cell from its outer environment.
Therefore, the statement "the tail portion of the phospholipid molecule is hydrophobic" is definitely true.
