Hormones are _____. See Concept 45.1 (Page) View Available Hint(s)for Part A signals that must interact with DNA in order to be effective chemical signals between cells, transported in blood or hemolymph always proteins are all under the control of the pituitary gland produced only in response to environmental stress
Answer:
The correct answer is - chemical signals between cells, transported in blood or hemolymph
Explanation:
Hormones are chemicals that make communication between cells and transfer the signals to various target cells. These are transported through the blood and lumph in their respective circulation so signals can reach to the surface or within the target cells and perform specific functions.
Climate change is expected to alter the ocean’s temperature, salinity, acidity, and currents. What would you want to investigate to find out how these changes would affect the way oceanic bacteria will process dissolved organic carbon in the future?
Answer:
Even though an individual phytoplankton is tiny, there are many of them in the ocean. Their combined effect on atmospheric CO2 is comparable to that of every plant on land. ... Then they exude altered dissolved organic carbon into the water (the bacterial equivalent of pee and poop) and respire carbon dioxide into the air.

What is "Radioactive Dating"?
A. A method of determining the age of a fossil that estimates the age of the organism at its death
B. A method of determining the age of a fossil based on the amount of certain isotopes that remain in a fossil or rock
C. A method of determining the age of a fossil that estimates how closely related various fossilized organisms were
D. A method of determining the age of fossil based on a comparison to the age of other similar fossils
Answer:
Unlike relative dating methods, absolute dating methods provide chronological estimates of the age of certain geological materials associated with fossils, and even direct age measurements of the fossil material itself.
Annette has her thyroid gland removed because of a malignant tumor. She takes synthetic thyroid hormone to replace the thyroxine that her thyroid gland would have produced, but she is worried about her blood calcium level since she has lost her source of calcitonin. Does she need to worry about this problem
Answer:
She doesn't need to worry if her parathyroid glands are working.
Explanation:
Although Annette has to worry about the impacts of thyroid gland removal and synthetic thyroid hormone intake, the calcium levels in her body need not be a concern as long as her parathyroid glands are functioning normally.
This is because the parathyroid glands are responsible for regulating calcium levels in the blood, through the production of parathyroid hormones or parathormone.
Using a simple aproxamation above,calculate the volume of the right circular cylinder with a radius of 2 meters and a height of 9 m
Answer:
Volume = 113.112 m³
Explanation:
Given the following data;
Radius = 2 meters
Height = 9 meters
To find the volume of a right circular cylinder;
The volume of a right circular cylinder is calculated by multiplying the area of its circular base with the height of the cylinder.
Mathematically, the volume of a right circular cylinder is given by the formula;
Volume= πr²h
Where;
r is the radius of the circular base.
h is the height of the cylinder.
Substituting the values into the formula, we have;
Volume = 3.142 * (2)² * 9
Volume = 3.142 * 4 * 9
Volume = 113.112 m³
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier. Group of answer choices
Complete question:
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.
Group of answer choices
A) behavioral . . . prezygotic
B) mechanical . . . postzygotic
C) temporal . . . prezygotic
D) gametic . . . postzygotic
Answer:
A) behavioral . . . prezygotic
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
There are different types of reproductive barriers.
Pre-copulatory o pre-ziygotic:
Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.
If a cell has 10 chromosomes when it begins mitosis, how many will it have immediately afterword?
Answer:
Explanation:
Therefore, there will be two daughter cells at the end of mitosis. Each will have 10 chromosomes, if the parent cell has 10. The chromsomes will not have sister chromatids because after mitosis, the duplicated pairs have separated into the two daughter cells. The cells will each be diploid, just as the parent cell was.
Explanation:
If a cell has 10 chromosomes when it begins mitosis, there are 15 will have immediately afterword.

The introduction of some nonnative species has been helpful. How can initially useful organisms become harmful to an ecosystem?
Answer:
See explanation
Explanation:
The introduction of nonnative species in an ecosystem maybe both helpful and harmful. Initially, the introduced nonnative species maybe prove helpful in some ways.
As time goes on, the nonnative species begin to compete with the native species for resources in the ecosystem. The nonnative species may outdo the native species in such competition and entirely replace them. This may ultimately lead to a permanent loss of the native species from the ecosystem.

¿Cuál se considera la “barrera simbólica” del nivel de CO2 en la atmosfera? ¿Cuál es el nivel de CO2 en la actualidad? ¿Qué significa esto? Menciona tres consecuencias de esta situación.
Answer:
413,55 ppm
Explicación:
413,55 ppm es el nivel de dióxido de carbono actual en comparación con el nivel de dióxido de carbono que es de aproximadamente 280 ppm antes de la revolución industrial. Esto significa que la revolución industrial aumenta la concentración de gas dióxido de carbono en la atmósfera, que es la principal causa del derretimiento de los glaciares, el cambio climático y el calentamiento global. Hay una gran cantidad de dióxido de carbono que se libera de las industrias, lo que es responsable del aumento de la concentración de dióxido de carbono en la atmósfera.

If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, what mutation must have occurred?
A. A nondisjunction mutation in the gamete of one of the parents
B. A nondisjunction in both gametes of the parents
C. A nondisjunction in one of the first gamete cells of the individual
D. A nondisjunction mutation in body cells of both parents
Answer:
if An individual has an extra chromosome in every one of its cells, the mutation that must have occurred is A non-disjunction mutation in the gamete of one of the parents
If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, the mutation that must have occurred is A. A nondisjunction mutation in the gamete of one of the parents.
Down syndrome simply means a genetic disorder that is caused when there's an abnormal cell division that then leads to extra genetic material.
The effect of Down syndrome is the fact that it leads to an intellectual disability, developmental delays, and a distinct facial appearance.
The mutation that has occurred with someone that has a Down syndrome is the nondisjunction mutation in the gamete of one of the parents.

What would be the electrostatic force between two charges of equal magnitude if the distance between them is halved
Answer:
the forces between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them
Answer:
The force becomes 4 times as much when the distance is halved.
Explanation:
F1 = k*q1 * q2/r^2 = kq^2/r^2
F2 = kq^2/1 / (r/2)^2
Set up a proportion using F1/F2 as you reference.
Notice that you don't know any number that can be used in this equation. However k q^2 does not change as you move the two charges closer together. That being so, you can still show what happens to F1 and F2.
F1/F2 = 1/r^2 // 1/(r^2/4)
Take the denominator, invert the fraction and multiply. That creates another cancellation.
F1/F2 = 1/r^2 * r^2 /4 1
F1/F2 = r^2 // r^2/4 which allows you to cancel r^2
F1/F2 = 1/4 Now you need to interpret F1 and F2. Cross Multiply
4F1 = F2
In an experiment, researchers find that certain neurons in the visual cortex preferentially fire in response to a bar of light that is oriented at a specific angle, and that different neurons similarly respond to bars of light oriented at different angles. This finding provides the strongest evidence for:
Answer:
Feature detection
Explanation:
Feature detection involves different neurons that are activated in response to specific stimuli. For example, feature detectors are activated in the cerebral cortex through visual stimuli of specific shapes or patterns. These neurons become more and more complex as the stimuli also become progressively more complex and specific. Featured detector neurons have been identified in the toad vision, where they have been involved in the toad's behavior in response to worm-like moving stimuli (e.g., orienting), and the bat auditory cortex, where they have been involved in the measurement of the distance between the bat and its prey.
