Ο Ο Ο Ο
C.
All the body cells are controlled by checkpoints.
d.
All the body cells arise from mitotic divisions of the same fertilized egg.
Answer: d. All the body cells arise from mitotic divisions of the same fertilized egg.
Explanation:
After conception occurs and an egg is fertilized, mitosis takes place as the egg begins to divide into other cells. This is how all the cells in the body are eventually formed regardless of how specialized their roles are.
As a result, every cell in the human body shares the same genes so any biological liquid or structure of the body would indicate the criminal because they would share the same gene as the rest of the cells in the criminal.
What is true of the molecules of DNA produced in replication?
Answer:
they are the same
Explanation:
Answer:
During replication, the DNA molecule separates into two strands and then produces two new complementary strands following the rules of base pairing. ... As each new strand forms, new bases are added following the rules of base pairing. The result is two DNA molecules identical to each other and to the original molecule.

The gravitational force between two objects will be very small, unless...
Group of answer choices
the objects are very far apart
the objects have very large masses
the objects are in the solid state of matter
the objects are spinning
Answer:
the objects have very large masses or an object in circular orbit. This has motion but its always being to pulled to earth by gravity.
Greater gravitational forces will be used to attract heavier things, since the gravitational force is directly proportional to the mass of both interacting objects. Two objects are attracted to one another by gravity as their respective masses increase. Thus, option B is correct.
What is the role of large masses in gravitation force?The gravitational pull between two objects changes inversely with their squared distance and directly with their large masses.
As a result, the gravitational force between the two items would decrease to one-fourth of its initial strength when the large masses of both objects are halved without affecting their distance.
Therefore, The objects are either in a circular orbit or have extremely large masses. Although something is moving, gravity is always bringing it dangerously close to the ground.

o You have encountered G-protein coupled receptors in Intro Bio I lecture, and will encounter them briefly again in Intro Bio II. You will spend 2 or 3 lectures on them in Cell Bio. They are integral (transmembrane) proteins embedded in the plasma membrane of every eukaryotic cell in your body. We will treat them as being 50 Angstroms in diameter. Considering the plasma membrane scaled up to the 4-inch baseline of the worked example in the lab powerpoint, how large would the G-protein coupled receptor be
Answer:
2 inches
Explanation:
Given that
The actual thickness of plasma membrane = 10 nm =10 * 10^-9 m
Diameter of G-protein = 50 * 10^-10 m
first step; determine the ratio of the actual thickness to the diameter of G-protein
= ( 10 * 10^-9 ) / ( 50 * 10^-10 )
= 2 ( this shows that the thickness of plasma is twice the diameter of the G-protein) .
considering that the plasma membrane is scaled up to 4 inch
The G-protein coupled receptor will be = 4 / 2 = 2 inches

Answer:
The organism's body parts would harden.
Explanation:
Your question is a bit confusing.
As per the image figure the corals live in calcium deposits and they have a hard exoskeleton. After the death of the organisms, the skin will remain the same.
What are corals?The corals are marine invertebrate species that live in colonies and feed on lime they develop in coral polyps and represent a sac-like animal.
They have an exoskeleton that remains after they die. They, can soft, stay, and spongy corals. A coral skeleton is a mineral plus organic matter.
The coral species harden from the outside while they are alive from inside like the roots of plants. Shows signs of evolution and life.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g). A student performed a cross between a plant that produced green melons and a plant that produced yellow melons. When the student observed the next generation, the 94 seeds that were produced from the cross matured into 53 plants with green melons and 41 plants with yellow melons. Calculate the chi-squared value for the null hypothesis that the green-melon parent was heterozygous for the melon-color gene.
Answer:
4.26
Explanation:
Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.
Observed(o) Expected(e) (o-e) [tex]$(o-e)^2$[/tex] [tex]$(o-e)^2/e$[/tex]
Green-melon plant 53 47 6 36 0.766
Yellow-melon plant 41 47 -6 36 0.766
Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

A geneticist studied the genome of a child. The geneticist discovered that the genetic
material of the child had three copies of chromosome 13.
How would the geneticist learn this type of information about the child's genome?
Answer:
through karyotyping
Explanation:
The geneticist can learn information about the child's genome through karyotyping.
Karyotyping is a process of analyzing the genome of organisms by first isolating the chromosomes of the organisms after which they are paired and ordered to provide a snapshot of their entire chromosome.
Thus, through karyotyping, all the chromosome sets of organisms can be analyzed and any abnormality detected. Chromosomes that are similar can be further analyzed and discovered to be copies of each other.
Therefore, the geneticist could have learned the information of the child having three copies of chromosome 13 through karyotyping of the child's genome.

What hormone helps plants move toward a stimulus?
A.)Ethylene
B.)Auxins
C.)Acids
Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance

There are ongoing arguments among taxonomists as to which phyla represent the closest relatives of phylum Annelida. Some propose that these worms share a common ancestor with the arthropods (crabs, insects etc.). However, the majority continue to keep the annelids lumped together with the Lophotrochozoa. The reasons for this are many but probably the least disputed comes from:______.
a. the segmented body plan of the annelids.
b. molecular analysis.
c. metamerism.
d. schizocoelous origin of the coelom.
Answer:
a. the segmented body plan of the annelids
Explanation:
lophotrochozoan is a taxonomy of animals that includes annelids, bryozoans, and brachiopods. This taxonomy of creatures was defined in 1995 as the last ancestor of the taxa of worms, mollusks, and annelids. Their classical definition depends on the topology of the spiral tree of life. Annelids have a segmented body part wherein the external morphological features are repeated in every body segment. It allows the animal to become bigger and makes their movement more fat and efficient.Answer:
B: Molecular Analysis
