Dogs have 39 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each dog cell?
Answer:
39 daughter chromosomes
Explanation:
This question is describing the MITOTIC process, which involves the synthesis of two daughter cells from one parent cell. In mitosis, sister chromatids, which forms a chromosome, separates at their centromere to become individual chromosomes in their respective daughter cells.
N.B: Mitosis produces two daughter cells which are identical in chromosome number.
In this case, a dog is said to have 39 chromosomes in its diploid cell. Since two chromatids make up one chromosome, 78 chromatids will be found in the dog cell. The 78 sister chromatids that form 39 chromosomes will each separate at their centromere to form 39 daughter chromosomes in each daughter dog cell.

What process moves energy from Earth's surface to high in the troposphere?
a. solar energy
b. conduction
C. convection
d. the nitrogen cycle
Answer:
Explanation:
Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. The rate of energy transfer by conduction is higher when there is a large temperature difference between the substances that are in contact.

Which of the following characteristics is shared by all modern living systems?
A. Multicellular body systems
B. Codons based on a triplet code
C. DNA as the genetic material
D. Sub-cellular organelles
Answer:
B-Condon's based on a triplet code
Expl
The characteristic shared by all modern living systems among the options provided is DNA as the genetic material. Therefore option C is correct.
DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions for the development, functioning, and reproduction of all known living organisms. It is a long, double-stranded helix structure composed of nucleotides.
Thus, DNA as the genetic material is a fundamental characteristic shared by all known modern living systems.
It encodes the instructions necessary for the development and functioning of an organism, allowing for the transmission of genetic information from one generation to the next.

Explain how scientists use geologic time to determine the age of landforms.
Answer:
Explanation:Following are the techniques or methods or approaches we can say that were used by the scientists to determine the geologic age:
1. Relative age dating
2. Absolute age dating.
3. Radiation measurement.
4. Stratigraphic superposition.
5. The fossil record.
The scientists used the method of relative dating to divide Earth's past in different chunks of time when alike organisms were on Earth. After that, to discover the actual number of years ago that events occurred, the scientists used the method of absolute dating.
PLEASE HELP!!! A scientist concludes that genetic inheritance of a mutated (changed) gene, such as a gene change that creates different-colored organisms in a population, is more beneficial to an organism over time and contributes to biological fitness. Discuss why a scientist would make that claim.
i posted a few min. ago and someone stole 30 points by answering and saying they couldnt help. please answer the question if you can and dont steal my points....
Answer:
When the organism inherits a mutated gene creating new colored organisms into the population, this can increase diversity. As more organisms inherit the same mutation, the population will become more variated, which can increase the organisms abilities to survive and adapt in a changing environment, and also improve the biological fitness of individuals; resulting in allowing more organisms to reproduce successfully.

Which statement describes photosynthesis?
a. Carbon dioxide and water combine to form glucose and oxygen.
b. Carbon dioxide and glucose combine to produce energy and water.
c. Carbon dioxide, glucose, and water are released to produce energy.
d. Carbon dioxide and water are released when glucose and oxygen combine.
Answer:
Your answer is A). In the presence of sunlight, plants take in the CO2 that we breathe out, and absorb water from the ground to make glucose (which the plant will use for energy when the sun isn't out), and oxygen which we breathe in again.

Which statement describes an interaction between the biosphere and the atmosphere that is related to
photosynthesis?
A.During photosynthesis, plant roots take in water from soil.
B.During photosynthesis, plants take in carbon dioxide from the air.
C.Through photosynthesis, energy stored in plants is released into the air.
D.Through photosynthesis, energy stored in plants is transferred to humans who eat them.
Answer:
B.During photosynthesis, plants take in carbon dioxide from the air.
Explanation:
A.During photosynthesis, plant roots take in water from soil. - water is part of the hydrosphere, not the atmosphere.
B.During photosynthesis, plants take in carbon dioxide from the air. - this is true, the plant - a living thing and part of the biosphere - takes carbon dioxide from the atmosphere to use during photosynthesis.
C.Through photosynthesis, energy stored in plants is released into the air. - this is false, plants release oxygen into the atmosphere as part of photosynthesis , which synthesises glucose. It does not release energy.
D.Through photosynthesis, energy stored in plants is transferred to humans who eat them. - this is true, but does not involve the atmosphere (air in the environment)
Based on Figure 1, which of the following statements best describes the epinephrine signaling pathway?
Group of answer choices
It involves the opening and closing of ion channels.
In involves enzymes activating other enzymes.
It involves changes in the expression of target genes.
It involves protons moving down a concentration gradient.
Answer:
It involves enzymes activating other enzymes.
Explanation:
Epinephrine activates glycolysis (i.e., glycogen breakdown) in skeletal muscle and at a lower level in the liver, which is more responsive to glucagon. When epinephrine binds to a G protein-coupled receptor, the receptor changes its conformation and then triggers a molecular cascade that involves the production of cyclic adenosine monophosphate (cAMP), a well known second messenger molecule in signal transduction pathways. Moreover, the beta-2 adrenergic receptor (ADRB2) is a G-protein-coupled receptor known to activate adenylate cyclase enzyme that leads to appropriate increases in cAMP and activation of protein kinase A (PKA).
Based on Figure 1, the statement that best describes the epinephrine signaling pathway is:
B. It involves enzymes activating other enzymes.
Epinephrine signaling pathway occurs when the neurotransmitters in the body helps the hormones to communicate with the epinephrine.
When this happens, there is a reaction within the receptor, causing it to become active.
As a result of this, there is a binding with the G-protein receptor which releases the cyclic adenosine monophosphate (cAMP).
This in turn, activates the other enzymes.
Therefore, the correct answer is option B
