Respiration is a series of enzyme-catalyzed reactions. Looking at the data below what is the optimum temperature
for the enzymes responsible for respiration?

Answer:

Without hydrogen bonds, water molecules would move faster more rapidly, with less input of heat energy, causing the temperature to increase more for each calorie of heat added.

Explanation: This would also greatly reduce the amount of heat energy needed for phase changes from ice to liquid, and from liquid to vapor.

Answer: Not really a question but....Two molecules of water can form a hydrogen bond between them that is to say oxygen-hydrogen bonding; the simplest case, when only two molecules are present, is called the water dimer and is often used as a model system.

nucleotide, phosphate

Answer:

fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.

Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.

Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.

Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.

Answer:

The correct answer is - option C. endocytosis.

Explanation:

Endocytosis is the transfer process of large molecules from the outside of the cells by internalizing them or engulfing them in vesicles, it is possible by invagination of the surface of the cell to form vesicles.

In an infant, the antibodies like large molecules from the mother to the baby are transferred through the Mother's milk which is entered in the baby's digestive tract via Endocytosis

Answer:

respiratory- breathing

Circulatory- blood flow

Explanation:

Animals are often individually consistent in their behavior, not only over time, but also across different functional contexts. Recent research has focused on phenotypic and evolutionary mechanisms explaining such personality differences through selection. Parasitism and predation induce important mortality and fitness costs, and are thus main candidates to create and maintain personality differences in the wild. Here, we present data on the behavioral consistency of the Eurasian minnow (Phoxinus phoxinus) from two populations that live in different tributaries of the same river, but whose ecological environment differs fundamentally with regard to predation and parasitism. We experimentally demonstrate that individual minnow in both study populations are consistent in their boldness and activity. However, the two study populations differ notably: in the high predation and parasitism risk population fish show higher mean boldness, but tend to be less active than fish in low predation and parasitism risk population. Parasite (Diplostomum phoxini) load was negatively, but not statistically significantly, associated with fish activity level. Our study suggests that parasitism and predation are likely important agents in the ecology and evolution of animal personalities.

Answer:

At least one organism benefits from commensalism.

Explanation:

The symbiotic relationship of commensalism is when one organism benefits and the other organism receives neither benefit nor harm.

So, this statement is true, because at least one organism has to benefit from the relationship, while the other will not be harmed or helped.

The biogeochemical cycle of water, or the hydrological cycle describes the way that water (Hydrogen Dioxide or H 2 O) is circulated and recycled throughout Earth’s systems. All living organisms, without exception, need water to survive and grow, making it one of the most important substances on Earth.

hope that helps

Biogeochemical cycles represent the main system where the energy of the Sun is converted into the energy of chemical compounds by living beings and the products of their activity.

A biogeochemical cycle is defined as the path by which a chemical substance cycles through the biotic and abiotic compartments of the Earth where the biotic factor is the biosphere and the abiotic factors are the atmosphere, hydrosphere and lithosphere.

Nutrients cycle occur through organic components as well as abiotic components. In biosphere the term bio refers to biotic components while 'geo' refers to abiotic components. Therefore, nutrient cycles in nature are called biogeochemical cycles.

Thus, Biogeochemical cycles represent the main system where the energy of the Sun is converted into the energy of chemical compounds by living beings and the products of their activity.

Answer:

Explanation:

5 ( x + 3 ) - 4 = 8 ( x + 3 ) - 4

5x + 15 - 4 = 8x + 24 - 4

5x + 11 = 8x + 20

By substituting,

5x - 8x = 20 - 11

-3x = 9

x = -9 / 3

x = -3

So the correct option is D

Answer:The fizzing of soda is a physical change that involves the release of gaseous carbon dioxide. During fizzing of a soda, you can see bubbles of carbon dioxide in the soda rise to the top. A bottle of soda doesn't fizz when it is closed because the pressure is higher, and keeps the carbon dioxide dissolved in the liquid.

Answer: RNA leaves the nucleus

Explanation: I did the assigment and got it right

1. RNA leaves the nucleus during both DNA replication and protein production.

What is DNA replication?

"DNA replication is the process by which the genome's DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome."

What are the main steps involved in DNA replication?

The main steps involved in DNA replication are as follows:

What is protein production?

"Protein production is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus."

What are the main steps of protein production?

Protein production includes three steps:

Answer:

The statement which best accounts for the decline of the bighorn sheep population is - " Human activities directly and indirectly affected the sheep."

Explanation: Explaination of the following statements -

Predation is rarely considered a major mortality factor (Wishart 1975, 1978). It is well known that bighorn sheep are preyed upon, but there is little information available on the effect(s) of predation on the populations of bighorn sheep. Numerous citations document the stalking and/or killing of bighorn sheep by a number of predators.

Thus , this statement is not correct.

Thus , the statement does not match with the decline of the bighorn sheep.

Hence, this statement is correct .

Home to 400 to 600 bighorn sheep, Glacier National Park lists the animal as a "species of concern," that is, at risk of being endangered.  The research has also shown just how sheep-like bighorns could be. They're creatures of habit, that is.  Therefore , the national park indicated the species at risk , but were not responsible for their declination.

Hence, this statement is incorrect.

Therefore , the correct answer is 3 ( Human activities directly and indirectly affected the sheep.)

Answer:

The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. Solar energy absorbed at Earth's surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it.

Answer:

Soil nutrient loss

Algae blooms

Pollution of water ways

Explanation:

Soil nutrient loss - a major concern as when soil erodes, this results in nutrient run off. Heavy rains can "wash away" essential nutrients within the soil therefore reducing the fertility of the land.

Algae blooms - when nutrients run off soil as a result of soil erosion they can leech into nearby fresh stream and even into salt water marine environments. This large increase of nutrients results in algae thriving and forming a layer across the top of the water. This reduces the oxygen and sunlight available to other marine plants and essentially suffocates plant and animal species.

Pollution of water ways - The sediment of soil that is eroded makes its way into fresh water ways can not only "bury" plant species and reduce biodiversity but it also reduces the water quality. It can introduce pathogens to the water from liverstock farming as well as introducing pesticides that may be harmful to wildlife.
