As lactose approaches the active site of lactase, as shown in the image, which of the following occurs first?

The lactose molecule is broken into glucose and galactose.
Lactase shifts to its lowest free energy level to allow lactose to enter the active site.
Lactose creates a microenvironment as it approaches lactase to promote binding.
Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Answers

Answer 1

Answer:

There is no image attachment, however, this question can be answered based on general understanding of enzymes. The answer is:

Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Explanation:

Enzymes are proteinous molecules that acts as catalyst in biochemical reactions by speeding up the rate of reactions. According to this question, lactase is an enzyme that acts on lactose sugar and breaks it down into its monomeric unit (glucose and galactose).

All enzymes possess an active site, with which they bind to their substrate. In this question, the lactose (substrate) approaches the active site of lactase (enzyme), what occurs first is that a temporary bonding occurs between the active site and the substrate, causing a conformational change in the shape of the enzyme.

After the 2004 tsunami disaster in Asia, there were reports that trained elephants had moved away

from the coastline before the tsunami struck. Scientists wondered if elephants had sensed the oncoming wave and the earthquake that created it. Elephant trunks have two kinds of nerve endings that are sensitive to pressure differences, but little is known about nerve ending distribution in the elephant's skin or feet. An elephant has recently died at a nearby zoo and scientists have decided

to dissect one of its feet to search for any special nerve endings. Results show a high density of pressure-sensitive nerve endings in the front of the foot and along the edges, which supports the

idea that elephants are sensing seismic signals produced by such disasters as earthquakes.


1. Independent variable

2. Dependent variable

4. Constant

5.controls

6.hypothesis

7. Sample size

8. Presence of repeated measures

Answers

Answer:

In the given dissection for the finding of the idea that elephant can sense the seismic signals generated by natural disasters are as follows:

Independent variable: it is the variable which influences the dependent variable or the dependent variable depends on. Here the area of the feet that is chosen to be dissected is the independent variable.

Dependent variable: It is the variable that is manipulated or influenced by the independent variable, in this dissection the sensitive to the pressure, nerve ending in the selected area of the feet.

Constants: It is a variable that remains constant or fixed in the complete experiment. The number of the selection area is constant hat is in one foot here.

Controls: There is no such control present in this experiment However, the density of pressure-sensitive nerve endings can be considered as control.

Hypothesis: the pressure-sensitive ending is significantly enriched in the feet of the elephant.

Sample size: subject in this study is only one elephant and one foot so the sample size is 1.

Presence of repeated measures: Repeated measures are not performed during this study is only one experiment of dissection is performed on a single subject.

A radioactive substance has a half-life of 1.25 million years. What is the age of a rock in which 6.25% of the original radioactive atoms remain? 5 million years old 6.25 million years old 3.75 million years old6 2.5 million years old 1.25 million years old 625 thousand years old

Answers

Answer:

The age of the rock is 5 million years

Explanation:

Fraction of radioactive substance remaining = 6.25% = 625/10000 = 1/16

Number of half-lives undergone by the substance to leave behind 1/16 of the original sample

1/16 = (1/2) * (1/2) * (1/2) *(1/2)

Therefore, the substance have decayed 4 times

One half=life = 1.25 million years

Four half-lives = 4 * 1.25 million years = 5 million years

Therefore, the age of the rock is 5 million years

Answers

Answer:

C. Net Primary productivity

Explanation:

In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.

The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R

Where, R = energy lost via respiration.

identify 3 abiotic factors and their roles in the economy in your own words

Answers

Answer:

Abiotic factors are the non-living parts of the environment that have a major influence

on living organisms. They can help determine things like how tall trees grow, where

animals and plants are found, and why birds migrate. The most important abiotic factors

include water, sunlight, oxygen, soil and temperature.

Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All

living organisms need water. In fact, water makes up at least 50% of almost all living

things. Some organisms are made up of 95% water! Water is also essential because

other substances easily dissolve into it. This allows water to carry nutrients to cells and

wastes away from them. Without water, animals become weak and confused, and they

can die if they don’t get enough water. Think of how you feel after you take a long run.

Do you feel thirsty? This is your body signaling to you that you need water.

Sunlight is the main source of energy on Earth, which makes it an extremely important

abiotic factor. Sunlight is necessary for photosynthesis, the process where plants use

carbon dioxide (CO2) and water to make sugar – food for the plants that later becomes

food for animals. Without the sun, plants could not live, and without plants, animals could

not live! Sunlight is also plays a role in the production of oxygen and to an area’s

temperature, which are discussed in detail below.

Like water, oxygen (O2) is another important abiotic factor for most living organisms.

Oxygen is used by cells as an energy source. It gives cells the energy they need to carry

out important functions, for growth, and reproduction. Without oxygen, humans and the

other organisms that use oxygen would not be able to live! Oxygen is produced by green

plants through the process of photosynthesis, and is therefore directly linked to sunlight.

Soil is considered an abiotic factor since it is mostly made up of small particles of rock

(sand and clay) mixed with decomposed plants and animals. Plants use their roots to get

water and nutrients from the soil. Soils are different from place to place – this can be a

big factor in which plants and animals live in a certain area.

Temperature is an abiotic factor that is strongly influenced by sunlight. Because the

amount and strength of sunlight varies by location, the earth’s surface has different

temperatures in different zones. While some animals and plants can bear extreme heat

or extreme cold, others can only survive well in moderate temperature ranges. In fact, all

plants and animals are adapted to survive between a minimum and maximum range of

temperatures. For example, a penguin from the polar region couldn’t live in a 110°F

desert. It would be too hot! Temperature, then, helps to influence which plants and

animals can live in an area.

ATP can convert to ADP during ___________.

Answers

Answer:

phosphorylation

Explanation:

ATP usually releases energy by breaking down the weak phosphate cell present.  The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. The weak bond between the second and the third phosphate is always targeted for turning ATP to ADP. This is the reason ATP is considered the main energy currency for the cell.
