Greg Performed An Experiment In Which He Measured The Reaction Rate Of Two Different Enzymes At Varying

Answers

Answer 1

Answer:

B. Enzymes have particular pH's at which they function best

Explanation:

The table in this question describes the reaction rate of two enzymes (enzyme 1 and 2) measured in mmol/min. According to the question, Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH.

At pH 7-9, the reaction rate of enzyme 1 was more than that of enzyme 2 while from pH 9.5-11, the reverse was the case. This portrays that the reactivity of an enzyme is in response to the pH they are placed in. In other words, different enzymes have particular pH's at which they function best.

Which of these is TRUE of a neuron at resting potential?
O The neuron has more positive charges inside than outside.
O Sodium-potassium pumps transport sodium ions into the neuron.
O Sodium-potassium pumps transport potassium ions out of the neuron.
O The neuron has more potassium ions inside than outside.

Answers

Answer:

O The neuron has more potassium ions inside than outside.

Explanation:

The membrane resting potential is defined as the difference in electrical charge between the interior of neurons and their outer environment. In neurons, both sodium (Na+) and potassium (K+) pumps contribute to generating the resting potential. Neurons have a higher concentration of K+ inside than outside and a higher concentration of Na+ outside than inside. When a neuron is at its rest state, where the inside is negative with respect to the outside, its membrane is more permeable to K+ than Na+, and therefore the resting membrane potential is closer to the equilibrium potential of K+.

Answer option

Parasitic relationship

Answers

i believe it is predator prey, the coyote is the predator, and the rabbit is the prey. they both are not competing for food(eliminating competition) , neither are both of them benefited.

Answers

Answer:

it is c: glycolysis

Explanation:

its correct on edmentum

Glycolysis is a process of biochemical importance which receives a supply of NAD+ions from the fermentation process during anaerobic respiration. Therefore, option (C) is correct.

Glycolysis  occurs in both aerobic and anaerobic respiration and is a  metabolic process. During anaerobic respiration, glycolysis is the only process that produces ATP.

In the absence of oxygen, the electron transport chain cannot function, and therefore, the Krebs cycle and electron transport system are not active. Therefore, glycolysis is the correct answer.

Describe passive and active freezing protections that could be set in place for an orchard of apples being grown in New York State and explain why they might be effective.
3 SENTENCES AT THE LEAST

Answers

Answer:

A good answer could include planting the trees on the north-facing flank of a hill (passive) and providing overhead irrigation to allow the grower to give plants an ice coating (active). Apples grown in New York face their strongest threat during bloom-time. North-facing plantings partway up a hillside delays bloom-time to later in spring, reducing the odds of the plants experiencing a hard frost. Irrigation allows the grower to take advantage of the severe overall cold that can be associated with a freeze in upstate New York by using the cold to create a protective ice layer that can preserve the blossoms.

Explanation:

this is the example answer. do what you will w it

The passive and active freezing protections can be done by planting facing north hill and providing overhead irrigation respectively.

What is Protection?

This is the process of guarding something against damage from an external force.

The passive and active freezing protections are effective as it minimizes the risk of freezes and frosts during spring blooms.

Which of the following is NOT a function of the stem in a plant?
o absorb water

O support flowers and leaves

Answers

Answer: Absorb water

Explanation: i took the quiz the other guy is wrong

Absorbing the water from soil is function of root and not a stem. Thus, option B is correct.

What is stem?

The structural part of plant, that supports leaves, flowers, and fruits is called as stem. Stems are frequently differentiated for storage, asexual reproduction, protection, or photosynthesis.

The stem is divided into nodes and internodes. Node consist of buds and leaves, that can grow into the branches. It also gives rise to adventitious roots. The function of internode is to distance one node from another.

Stem supports and uprights leaves, flowers and fruits. The stem keeps the leaves in the light and provides the plant with a place to hold the flowers and fruit. It transports fluid between xylem and phloem roots and shoots. Therefore, transportation of water and nutrients is the function of stem, and not absorption. Hence, option B is correct.

DNA polymerase III is a holoenzyme, which has two core enzymes (Pol III), each consisting of three subunits (, and ), a sliding clamp that has two beta subunits, and a clamp-loading complex which has multiple subunits (, , , , and ).

Explanation:

The subunits used to make product in DNA replication are:

I. Alpha (α) subunit.

II. Delta ([tex]\delta[/tex]) subunit.

III. Epsilon ([tex]\epsilon[/tex]) subunit.

Nucleus is the most conspicuous cell organelle that is found in all eukaryotic living organisms.

Basically, the nucleus serves as the site for ribonucleic acid (RNA) synthesis and deoxyribonucleic acid (DNA) replication.

DNA replication can be defined as a biological process through which two identical replicas of deoxyribonucleic acid (DNA) molecules are produced from an original deoxyribonucleic acid (DNA) molecule, especially during cellular division.

This ultimately implies that, DNA replication is a biological process that occurs during cellular division and it involves the duplication of a double-stranded DNA to produce two identical deoxyribonucleic acid (DNA) molecules.

The three (3) main subunits (polymerases) used for making products in DNA replication includes the following:
