Cancer is caused by __________ in genes that regulate the cell cycle. These mistakes in DNA, cause the checkpoint __________ to not function properly. As a result the cells will spend more time dividing, which is called _____________ rather than in interphase.
Explanation:
cancer cause due to uncontrolled divisions of the cell because of gene mutations or presence of oncogenes which destroy or destabilise the checkpoints that prevent or controll cell division
which of these cells is the odd one out?: human skill cell, fungi cell, a or bacteria cell?

The electron transport chain produces much more ATP than glycolysis or the Krebs Cycle but it needs them to happen in order to take place. How do the first two steps make the last one possible?
Answer:
there is a link
Explanation:
glycolysis produces pyruvate which feeds into the krebs cycle
krebs cycle also generates redox agents(NADH and FADH2) needed in the etc

The transport of water through a plant depends on roots absorbing water. Roots depend on osmosis to obtain water. In osmosis, water always a. Moves from a high concentration to a lower concentration b. Moves from a lower concentration to a higher concentration c. Moves so that the concentration of water on one side of the cell membrane is higher than on the other side d. Moves until there is no water left on one side of the cell membrane

What is rule of dominance?
Answer:
Mendel's law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.

Which of the following kingdoms does NOT have members who are heterotrophic? A. Fungi B. Animalia C. Plants D. Protista (Dont send me a file)
Answer:
Plants
Explanation:
This is because plants kingdom are autotrophic that they are producers.
Plants kingdom are producers because the photosynthesized. The have chlorophyll which trap light energy from the sun and uses carbondioxide and water to produce carbohydrates and oxygen is released. Therefore they are not heterotrophic, they did not depend on other kingdom to feed...they are primary producers.
What’s the answer to this I didn’t mean to click this btw

Which of the following is not a random occurrence?
A selection of the best-suited traits for the environment, leading to adaptive evolution
Genetic drift changing the gene pool of a population and creating fluctuations in the allele frequencies
The bottleneck effect after an earthquake, resulting in a reduction of genetic variation
The founder effect, when a small population is isolated and the gene pool significantly reduced from the parent population
Answer: A selection of the best-suited traits for the environment, leading to adaptive evolution brainliest
Explanation:
What is true of the genetic makeup of all body cells in the human body except for sex cells?
Answer:
It is the same no matter what the cell type. It is random even within the same cell type. It is used to sort cells into organs based on chromosomal differences.
Explanation:
(13) Which part of the digestive system is mainly responsible for absorbing water?
A the large intestine
B the pancreas
C the small intestine
D the stomach
Answer:
C) the large intestine
Explanation:
95% of absorption of nutrients occurs in the small intestine. Water and minerals are reabsorbed back into the blood in the colon (large intestine) where the pH is slightly acidic about 5.6 ~ 6.9.

Which of these is NOT a factor contributing to the loss of biodiversity?
a
urbanization
b
climate change
c
planting of trees
d
over exploitation of species
Answer:
Option C
GOOD LUCK FOR THE FUTURE! :)
Planting of trees is not a factor contributing to the loss of biodiversity. Thus, option C is correct.
What is five kingdom classification?
The main purpose of the classification of the Five kingdom has been known R.H. Whittaker. The five kindoms that has were included in this proposal were the Fungi, Protista, Monera.
Animalia as well as the kingdom Plantae. There are mainly five criteria or the conditions based on which the classification has been madeup of. These criteria has been includes the structure of the cell, as well as the nutrition mode, organisation of the thallus, or the relations of reproduction and phylogenetic.
Based on shoe characteristics they were to develop a classification hierarchy of shoes, beginning with the shoe "kingdom" and becoming more and more specific, just like scientists did for the classification of living things.
Therefore, Planting of trees is not a factor contributing to the loss of biodiversity. Thus, option C is correct.

If a gray fly is crossed with a heterozygous black fly, which combination below represents the parental cross?
Answer:
hello your question lacks the required options hence I will give you a general answer
answer : gg ( gray fly ) * Gg ( heterozygous black fly )
Explanation:
Let black body ( G ) be the dominant allele to gray body ( g )
hence the possible combination that will represent a parental cross when a gray fly is crossed with a heterozygous Black fly will be
gg ( gray fly ) * Gg ( heterozygous black fly )
