Which best explains why the rate of a reaction decreases at significantly higher temperatures?

A. The activation energy increases.

B. The shape of the enzyme changes.

C. The enzyme-substrate complex forms.

D. The bonds between substrates are broken.

Answers

Answer 1

Answer:

B

Explanation:

At significantly higher temperatures, the rate of an enzyme-catalyzed reaction decreases because the shape of the enzyme changes at high temperatures. Enzymes are proteinous in nature, and as such, are generally sensitive to high temperatures.

They simply become denatured by high temperatures. In other words, they lose their original shape and their catalyzing abilities as the temperature gets progressively high during the course of reactions, thus, decreasing the rate of a reaction.

The correct option is, therefore, B.

Use the picture to explain how CONVECTION heat transfers could be responsible for the weather in our atmosphere.

Answer the question in 2-3 complete sentences.

Answers

Answer:

The sun's waves heat the ground, causing it to warm (radiation). The energy flows from the warmer ground to the cooler air (conduction), causing it to rise (convection). When the rising air reaches a certain point, it expands, cools, and the cooler expanded air can no longer hold as much water vapor so it rains.

In the female human reproductive system, eggs are created in an ovary, and implanted in the uterus. For the embryo to grow, it must receive nutrients and oxygen. This problem is solved through an organ called the A. Amniotic sac B. Placenta C. Uterus D. Umbilical cord

Answers

Answer:

The correct answer is D. Umbilical cord

Explanation:

The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).

Gene flow increases the chance for reproductive isolation which can cause new species to form.

Answers

Answer:

B . Gene flow between populations increases genetic diversity over time.

Explanation:

Gene flow affect populations when the Gene flow between populations increases genetic diversity over time ( option B )

The effect of gene flow is to reduce genetic differences between populations, thereby preventing or delaying the evolution of the populations in different geographical areas into separate species of the pathogen.

Gene flow

Gene flow is the movement of genes from one population to another population. It is the introduction of genetic material from one population of a species to another, thereby changing the composition of the gene pool of the receiving population.

Suppose if all the bones of the skull (facial bones) are fused together, which function would you not be able to carry out?

Answers

Answer:

to masticate food

Explanation:

In adults, all the bones of the skull, except one, are fused together by immovable joints referred to as sutures. The sutures are fibrous joints which hold the bones of the skull together to form a rigid and strong structure that protects the brain. Skull bones fuse around two-years (18 to 24 months after birth). The only skull bone that is not fused by sutures in adults is the mandible, which is used to masticate food.

How does the operator region of DNA work to regulate gene expression?

Answers

Answer:

Explanation:

Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.

Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.

Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.

What is food chain?

A food chain is defined as the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism.

The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain. A system of interlocking food chains is called a food web.
