View Available Hint(s) In evolutionary terms, an organism's relative fitness is measured by its __________. stability in the face of environmental change genetic variability contribution to the gene pool of the next generation health mutation rate Submit
Answer:
Following are the responses to the given choice:
Explanation:
Evolution includes the change in the heritage characteristics of the organism population as subsequent generations substitute each other. These were all communities of developing organisms but not single individuals. In evolutionary terms, the relative efficiency of an organism is assessed by its contribution to the next gen's gene pool.

Elaborar un Mapa Conceptual con datos cualitativos y cuantitativos procesados sobre los cromosomas, la terminología genética y caracteres hereditarios.
Answer:
Los cromosomas son componentes de células complejas (eucariotas) en las que se almacena la información genética necesaria para la herencia de propiedades. Un cromosoma contiene ácido desoxirribonucleico (ADN), en el que se codifican los genes, así como varias proteínas, especialmente histonas. En los organismos eucariotas, que incluyen plantas, hongos, animales y, por tanto, también seres humanos, los cromosomas son componentes regulares en el núcleo celular.

The diagram below shows molecules represented by X Both outside and inside the cell
A process that would result in the movement of these molecules out of the cell requires the use of
A-DNA
B-ATP
C-Antigens
D-Antibodies
Answer:
B. ATP
Explanation:
ATP would be needed to provide energy for the movement of the particles since the movement goes against the concentration gradient (So this is active transport)
A process that would result in the movement of these molecules out of the cell requires the use of ATP.
What is ATP?
A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers energy to cells by releasing its phosphate groups when it interacts with enzymes like ATP triphosphatase.
An adenine bicyclic system, a furanose ring, and a triphosphate chain make up the molecule. The principal energy source for critical biological processes such muscular contraction, nerve impulse transmission, and protein synthesis is ATP generated in mitochondria.
Therefore, A process that would result in the movement of these molecules out of the cell requires the use of ATP.

Nonmetals are defined as elements that generally cannot
conduct _____
and are poor conductors of heat.
Answer:
they can not conduct electricity
Non-metals are defined as elements that generally do not conduct electricity and are poor conductors of heat.
What are elements?
It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

The swordfish contains a heat generating organ that warms its brain and eyes up to 14°C above the surrounding ocean water temperature. Which structures are most likely to be found at relatively high concentrations within the cells of this heat generating organ?
A. nuclei
B. chloroplasts
C. chromosomes
D. mitochondria
Answer:
The mitochondria of a cell use up oxygen and nutrients from the body and convert them into energy and heat. The heat is used to maintain the temperature of the organs and body. Hence, the heat-generating organ would have the organelles, mitochondria, in abundance in its cells.
How could an error during transcription affect the protein that is produced
Answer:
The protein might be unable to function if an error during transcription occurs. Explanation: During transcription, the mRNA is formed. If the error encountered in the transcription, mRNA formed would be a transient one and would eventually get degraded.

Water molecules have a strong attraction to one another.
What property best describes this attraction?
Choose 1 answer:
A
Hydrophobic
B
Cohesion
C
Density
D
Adhesion
Answer:
The correct answer is B: Cohesion
Explanation:
Cohesion is the ability of water molecules to be strongly bonded together. This happens due to the polarity of water molecules. Since water is made up of two positive hydrogen ions that combine with one negative oxygen ion to form a hydrogen bond. Hence, the molecular structure of water enables hydrogen irons to attract oxygen ions that create a strong polar bond between water molecules.
