Metabolic rate is _____. See Concept 40.4 (Page) View Available Hint(s) Metabolic rate is _____. See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size
Answer:
The correct answer is ''the total amount of energy an animal uses in a unit of time''
Explanation:
The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.

Which is an endocrine function?
Answer:
Explanation:
The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.

On Earth, water is found naturally in all of these states EXCEPT ____
A. Gas
B. Liquid
C. Solid
D. Plasma
On Earth, water is found naturally in all of these states except plasma. So, the correct option is D.
What is Water?With the chemical formula H2O, water is a colorless, transparent, flavorless, and odorless chemical molecule. It is a straightforward molecule bound together by covalent connections and made up of two hydrogen atoms and one oxygen atom.
All known forms of life depend on water, which is the most plentiful material on the surface of the planet. Under typical temperature and pressure conditions, it is capable of existing in all three of the physical states of solid, liquid, and gas.
Water is an essential component of many natural and industrial processes since it is a universal solvent and can dissolve a wide variety of compounds. It is an essential part of the Earth's water cycle, and it's crucial for maintaining ecosystems and controlling temperature. On Earth, water is found naturally in all of the states such as gas, liquid and solid.
Therefore, the correct option is D.

This sea anemone and this ctenophora both have tentacles, which are body structures that help them catch food. However, sea anemone tentacles are short and can sting, while ctenophore tentacles are long for grabbing and cannot sting. What most likely explains why both species have tentacles and why the tentacles are different
Answer: Sea anemone and ctenophore both inherited tentacles from a shared ancestor population, but this population separated into different environments. In each environment, different types of tentacles evolved, which helped the populations survive.
Explanation:
most likely explains why both species have tentacles and why the tentacles are different is because sea anemone and ctenophore both inherited tentacles from a shared ancestor,
Then, this population separated into different environments and there was tye evolvement of different types of tentacles evolved, which therefore helped the populations survive.

24) is it possible to know the genotypes of the three children in generation 111?
should their shapes be shaded? explain your answer to both questions.
Answer:
The genotype of all children in generation III is Hh. as H comes from dad and h comes from the mother for every case.
yes, their figures should be shaded.
reason :-
The dominant allele Fort this disease is shown by H whereas the recessive trait shown by h.
each offspring in generation III has the genotype Hh
and the presence of one dominant allele is enough to cause the disease.
all children in generation 3 suffer from the disease and so their figures should be shaded
Which statement best explains how sewage systems help fight the spread of disease?A.They carry antibiotics that kill pathogens in the air.B.They add chlorine to drinking water before it is transported to homes.C.They kill the animals that spread pathogenic bacteria.D.They carry human waste to treatment facilities away from cities.
Answer:
D.They carry human waste to treatment facilities away from cities.
Explanation:
Sewage system is a collection of systems that carries sewage (human waste) from the point it was produced to a place where it'll be treated or recycled.
Since sewage is moved via the use of sewage system, it helps to fight the spread of disease by carrying human waste (sewage) to treatment facilities away from cities.

A pair of butterflies reproduces and has one thousand offspring. All one thousand of the offspring have the alleles Aa. What is the most likely combination of alleles (genotype) for each parent? Explain your answer.
Answer:
It is expected that each parent is homo-zygous for each trait (i.e., one parent has genotype AA and the other parent has genotype aa)
Explanation:
An F1 hybrid is the first filial generation of the progeny of distinctly different parental types. In this case, it is expected that each parent is homo-zygous for each trait, thereby 100% of all offspring will have genotype Aa (i.e., parental cross: AA x aa >> F1 = 100% Aa). On the other hand, in a cross where one parent is heterozygous for the trait (Aa) and the other parent is homo-zygous (either AA or aa), only 50% of all offspring will have genotype Aa.

CLAY PARTICLES DO NOT SETTLE DOWN EASILY DURING THE PROCESS OF SEDIMENTATION. CAN YOU SUGGEST ONE METHOD TO MAKE THEM HEAVIER AND THUS HELP IN SEDIMENTATION? Name the method and the chemical
Answer:
Coagulation by additionmof chemicals such as aluminium sulfate also known as alum will help in sedimentation of clay particles.
Explanation:
Clay particles are very small particles found suspended water obtained from streams and rivers for township supply. They have weak electrical negative charges on their surfaces which when they approach one another, they repel each other thus making it almost impossible for clay particles to settle out of suspension.
Because of this, prior to the sedimentation step, a chemical process known as coagulation is required. In this process, certain chemicals called coagulants, are added to the water to bring the difficult-to-settle suspended particles such as clay particles together into larger, heavier masses of solids called flocs. They do these by interfering with the repulsive forces between the particles, thus allowing them to clump together into flocs. The most commonly used coagulant used for water purification is aluminium sulfate or alum. Other chemicals that are also employed in coagulation include ferric sulfate and sodium aluminate.

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.
=============================================
For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.
Recall that
distance = rate*time
we can rearrange things to say
rate = distance/time
So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.
----------
So,
rate = distance/time
rate = (260 meters)/(180 seconds)
rate = (260/180) meters per second
rate = 1.44 meters per second, which is approximate
I'm rounding to 3 sig figs.

Todas las células no tenían pared celular. Sabemos que la célula animal es un tipo de célula que solo tiene membrana celular. Las células procariotas se originaron hace aproximadamente 3,5 mil millones de años. Los centríolos son orgánulos cilíndricos, formados por proteínas, que contribuyen en la división celular. El ADN determina las características de un organismo porque el ADN tiene toda la información sobre los organismos. La digestión celular no ocurrió en las mitocondrias. El lugar de la digestión celular son los lisosomas. En la definición de celda, la palabra estructural, se refiere a la composición y forma de la celda. La palabra eucariota significa "núcleo verdadero" y núcleo verdadero significa que la membrana rodea al núcleo.
