what is the temperature at which enzymes work best and worst?
Answer:
There is a certain temperature at which an enzyme's catalytic activity is at its greatest which is 37.5 oC
Enzymes are still proteins, and as with all proteins, temperatures above 104 degrees Fahrenheit, 40 degrees Celsius, will start to break them down.
Explanation:
The temperature for most enzymes is about 98.6 degrees Fahrenheit (37 degrees Celsius).There are also enzymes that work well at lower and higher temperatures.

Which of the following correctly matches a property of an organic molecule with how that property helps the organic molecule function in living organisms?
A. Carbohydrates lower the activation energy of certain reactions. This allows metabolic processes to take place at a rate that can sustain life.
B. Proteins contain nucleotides that encode genetic material. This allows proteins to accurately pass genetic information from one cell to another.
C. Nucleic acids contain multiple carbon-hydrogen bonds. This allows nucleic acids to provide energy for living organisms by breaking these bonds.
D. Lipids are insoluble in water. This allows lipids that make up biological membranes to regulate the entry and exit of many substances.

Explanation:
How is your body temperature held constant?
The elasticity of those capillaries plays a central role in our ability to maintain constant body temperatures. When there's too much heat in the body, our capillaries automatically expand and increase the blood flow to the skin, allowing the excess heat to transfer to the air.
How does flooding affect the soil layer of the
ecosystem?
Answer:
Changes from flooded to drained conditions in soils stimulate changes from aquatic to terrestrial vegetation and decrease the algal contribution to total primary production. Drainage of organic soils then has the effect of removing a source of net primary production (algae) and carbon sequestration
Explanation:
Use different words then I did
Answer:
Soil will become damp and will thrive in water
If a dog starts to put its paw down on a sharp stone, the tough skin skin protects underlying structures from damage. Additionally, touch receptors in the skin send sensory signals to the spinal cord. The spinal cord then sends a signal to the muscles to lift the paw rather than continuing to press down. In this scenario, the dog may experience discomfort but avoid injury.
What two body systems are being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw?
A.
integumentary and nervous systems
B.
circulatory and nervous systems
C.
circulatory and lymphatic systems
D.

The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.
What is the organ system?The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.
Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

What is the volume of 2.7 moles of N2 at STP?
Answer:
60.48L
Explanation:
By definition, at STP (Standard Temperature and Pressure), any gas takes up a volume of 22.4L.
Consequently, because the ideal gas law (PV=nRT) states that the number of moles is directly proportional to the volume of the gas, 2.7M of N2 takes up a volume of:
2.7*22.4L
=60.48L

Sperm cells swim through liquid. Explain how a sperm cell is adapted to reduce friction as it swims.
Answer:
Long tail and narrow head.
Explanation:
A sperm cell is adapted to reduce friction as it swims by having long head, narrow tail and enzymes. These features of sperm provides ability to swim straight to the egg cell. Long tail helps the sperm cell to swim towards the egg cell, narrow head of sperm cell make the sperm cell for faster swimming towards the egg cell and enzymes present in the head of the sperm helps break through the egg cell membrane so we can say that the long tail and narrow head of sperm cells helps in faster swimming.
The Competitive Exclusion Principle states that: Group of answer choices a. When two species occur together, competition is always prevented by some behavioral adjustment. b. Two species that use a limited resource in the same way cannot coexist indefinitely. c. Two species that use the same community can use limited resources in different ways. d. When two species each compete for the same resource in the same location, competition will always evolve into commensalism. e. None of the choices are correct.
Answer:
b. Two species that use a limited resource in the same way cannot coexist indefinitely
Explanation:
The competitive exclusion principle establishes that two or more species that share the same niche requirements, in the same habitat, and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. This is because species with identical niches have the same necessities, which means that they will compete for the same resources. If these species have the same requirements, they can not coexist. When the superior competitor occupies the inferior competitor´s fundamental niche, the first species has advantages over the second species and monopolizes all the resources. From that moment, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs or get extinct.
When two competing species coexist, this is because of niche partitioning or niche differentiation. One of the species uses a different resource, occupies another area, or uses the resources at different times during the day. If there is not any differentiation between them, the dominant species displaces the weak species.
Niche specialization might produce genotypic separation. Subpopulations of a species diverge into new species.
So, competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche.
Answer:
B. Two species that use a limited resource in the same way cannot coexist indefinitely.
Explanation:
The Competitive Exclusion Principle states that: Two species that use a limited resource in the same way cannot coexist indefinitely.
On the Bahamian island of Andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. Which type of reproductive isolation operates to keep the mosquitofish isolated, even when fish from different ponds are reunited in the same body of water
Answer:
The correct answer is - Behavioral isolation.
Explanation:
In the question, it is given that the mosquitofish of different habitat shows different behavior as per the availability of predators in the particular habitat. For instance, some mosquitofish can swim continuously for a long time in fewer predators area whereas predator-rich ponds have mosquitofish that can swim in short, fast bursts.
It is evident that they diverged from common species that isolated in different regions, their behavior got changed according to the presence of predators. Thus, the isolation is here, behavioral isolation.

In dogs, spotty fur is a recessive trait. Show a cross between two dogs that are heterozygous for spotty fur. What is the likelihood of these dogs having puppies with spotty fur?
Answer:
The correct answer is - 25% chances of having puppies with spotty fur.
Explanation:
In this question, it is given that spotty fur is a recessive character which means in the heterozygous condition it is not expressed in the phenotype. Here the cross between two heterozygous dogs for spotty fur will produce the following gametes:
Heterozygous: S and s where S is dominant allele and s is the allele for spotty fur that is recessive
Punnett square:
S s
S SS Ss
s Ss ss
By the Punnett square, we can say that likelihood of spotty fur (ss) in puppies is only 1/4 or 25%.
