Explanation:
what would happen if Jupiter's gravitational pull increased
Answer:
The amount of mass that planet Jupiter has in the solar system makes it approximately five times larger than all other planets in it. As Jupiter’s gravity pulled on another planet tightly, its diameter grew and it expanded. The density and gravity continued to increase, resulting in even more planet compression.

What kingdom is the organism in?
The kingdom of the organism in this scenario is referred to as a protist because it contains certain features such as being unicellular and possessing what we call DNA in its nucleus etc and is denoted as option D.
What is a Protist?This is classified as an eukaryotic organism which does not belong to the animal, plant, or fungus family. it is however unicellular and has the ability to produce food on their own which is responsible for their survival in the ecosystem.
These organisms produce food through the process known as photosynthesis and examples include algae, diatoms etc. They also have DNA enclosed in their nucleus which is why they are referred as being eukaryotic.
This is therefore the reason why protist was chosen as the most appropriate choice.

how many cells are in this picture? and which phase are most of the cells in-interphase, mitosis or cytokinesis
Answer:
~100 cells,
Explanation:
I counted around 102 cells in the picture. For your seond question I am a bit confused.
You asked what phase are they in and gave interphase, mitosis and cytokineses as the options. While interphase and cytokinesis are phases of mitosis. Therefore in theory all the cells are going through mitosis.
Since most of the cells are looking like dense balls, we can say they are going through interphase.
P.S. I also see some going through anaphase, metaphase and cytokinesis, but they are seldom in numbers compared to interphase cells.
Rock pocket mice are rodents native to the southwest. Normally, the rock pocket mice are tan colored rodents living in the sandy environment of the west. However, a mutation introduced an allele for dark fur. Scientists are now studying the populations of tan pocket mice living in the sandy environment along with the mutant black mice thriving on dark lava rock from an old lava flow. The rock pocket mice are living examples of evolution occurring today. Which of these statements DOES NOT support that idea?
A) Organisms develop mutations to help them survive.
B) Mutations that increase the fitness of an organism increase in frequency in a population.
C) The selection pressure can be different depending on the particular environment.
D) A mutation is a random change to an organism's DNA sequence
The statement does not support the idea "A mutation is a random chance to an organism's DNA sequence." This is further explained below.
What is a Rock pocket mice?Generally, this mouse is known for its avoidance of owls, it consumes mostly plant seeds and digs little tunnels in the dirt near or beneath rocks.
In conclusion, The visual predator favored the tan mice on the dark rock. Hence, A mutation is a not random change to an organism's DNA sequence.

Which of the following best describes prokaryotes and eukaryotes?
O Prokaryotes have a nucleus and eukaryotes do not.
O Prokaryotes do not have a nucleus, eukaryotes have a nucleus.
Both have membrane-bound structures
Prokaryotes have membrane-bound structures and eukaryotes have free floating organelles
Answer:
Prokaryotes do not have a nucleus, eukaryotes have a nucleus.
Explanation:
The prokaryote cells do not have a nucleus whereas eukaryotic cells have distinct a nucleus.
Eukaryotes are creatures made up of cells with membrane-bound organelles and a nucleus that contains DNA in the manner of chromosomes. Thus, option B is correct.
What are eukaryotes and prokaryotes?Prokaryotes and eukaryotes are the two classes into which all living things may be divided based on the basic makeup of their cells.
Prokaryotes are creatures consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryotes' DNA is not contained within a nucleus.
Eukaryotic organisms can have several cells or only one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.
Therefore, Prokaryotes do not have a nucleus, eukaryotes have a nucleus.

Explanation:
There is a maximum between the two input values -2 and 2.
A quadratic function is the function which has 2 as its highest power. Its genralised form is given as y=ax²+bx+c.
From the given table it can be observed that at extreme values of x, therefore, when x=-5 and x=9, the value of y is negative. Therefore, at any value above 9 and below -5, the value of the function will be always negative.
Further, it can be observed that the highest value of y is 9 which when the value of x is -1.
The only choice from the given option that includes -1 in its answer is -2 and 2.
To verify this a graph can be plotted for the function as shown below.
Hence, the maximum will be between -2 and 2.

But people all so arguw that Adaptation is it two
Answer:
Technically the first 3
Explanation:
Genes are segments of DNA that have code for a specific protein that functions in one or more types of cells. Chromosomes are structures in cells that contain a person's Genes. Genetic disorders can be caused by a mutation in one gene which is called a monogenic disorder.
The fourth one about traits is tricky to decipher as there are about 25 to 35 thousand genes in one cell that carry information inherited from your parents that determine your traits. If Chemical traits could be explained further in detail, this might be an option
butIi would say it would say point mutations
During the cell cycle, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. at the end of this cycle, the cyclins degrade to prevent further signaling for the cell to divide.
uncontrolled production of cyclins will most likely result in —
f) the formation of tumors
g) the immediate death of the cell
h) the transfer of cyclins to other cells
j) the formation of haploid cells
Uncontrolled production of cyclin proteins will most likely result in the formation of tumors (Option f).
What are cyclins?Cyclins are proteins that control the progression through the cell cycle by their interaction with specific kinases.
These cyclins-dependent kinases (cdks) can be phosphorylated as a control points during the cell cycle.
