1. Which of the following gases is need by plants?

Answers

Answer 1
Carbon dioxide because people in other animals exhale carbon dioxide as a waste product. People and other animals need oxygen for plants produce oxygen during an important process called photosynthesis which turns the sun energy into nutrients so carbon dioxide would be the answer.
Answer 2

Answer: Carbon dioxide

Explanation:

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

The decimal reduction time (DRT) to kill 90% of cell present for autoclaving a culture is 1.5 minutes. How long would it take to kill all the cells if 106 cells were present? What would happen if you stopped the heating process at 9 minutes?

Answers

Answer:

10.5minutes

Explanation:

DRT = 90%

Cells present = 10^6

Autoclaving = 1.5 minutes

Solution:

10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5

it would take it approximately 10.5 minutes to kill 10^6 of the cells.

If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

Given what you learned about how influenza changes over time, how could you explain the emergence of drug resistance in bacterial pathogens?

Answers

Answer:

Beneficial mutations events can generate resistance to drugs

Explanation:

Bacteria can develop antibiotic resistance through mutations, as well as horizontal transference events, that allow them to reduce/eliminate the effectiveness of drugs used to treat infections. For example, penicillin-resistant strains have been identified in Staphylococcus aureus and Streptococcus pneumoniae. In general, mutations have a negative impact on the fitness of the organism; however, there are cases where mutations increase the fitness of the individual. In consequence, antibiotic resistance may occur by natural selection, where antibiotic-resistant bacteria that exhibit beneficial mutations are selected to survive and perpetuate their genetic material.

Two different groups of scientists studying a rare trait in ground squirrels report very different heritabilities. What factors influencing heritability values make it possible for both conclusions to be correct?

Answers

Answer:

It is a trait highly influenced by environmental factors (i.e., it has low heritability)

Explanation:

In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.

How far do scientists estimate the plates move in a year

Answers

Answer:

10 cm

Explanation:

They can move at rates of up to four inches (10 centimeters) per year, but most move much slower than that. Different parts of a plate move at different speeds. The plates move in different directions, colliding, moving away from, and sliding past one another. Most plates are made of both oceanic and continental crust.

An experiment is designed to study the mechanism of sucrose uptake by plant cells. Cells are immersed in a sucrose solution, and the pH of the solution is monitored. Samples of the cells are taken at intervals, and their sucrose concentration is measured. The pH is observed to decrease until it reaches a steady, slightly acidic level, and then sucrose uptake begins. Rank the steps from first to last. To rank items as equivalent, overlap them.


A proton Pump, using ATP, pumps protons outside.

Sucrose moves into the cell.

Answer:

A proton Pump, using ATP, pumps protons outside

A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.

pH decreases;

The gradient becomes sufficient.

H+ moves down electrochemical gradient into the cell; Sucrose moves into the cell.

Explanation:

A proton Pump, using the energy of ATP hydrolysis, pumps protons outside the cell.

A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.

The continues outward pumping of protons by the proton pump causes the pH of the extracellular fluid to decrease

At some point the gradient becomes sufficient, and pH reaches a steady slightly acidic level.

H+ moves down its electrochemical gradient into the cell together with Sucrose through the hydrogen ion-sucrose co-transporter.

C) H+ moves down the electrochemical gradient into the cell.

A) A proton Pump, using ATP, pumps protons outside.

D) A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.

F) The gradient becomes sufficient.

A co-transporter also called a symporter, is a carrier protein that transports a solute and an ion from one side of the membrane to the other at the same time.

The proton pump is an integral protein that builds a proton gradient across a biological membrane.

The cell cannot import sucrose by simple diffusion, the cell expends energy to move the substance against a concentration gradient.

The sodium and potassium maintain the electrochemical gradient of living cells, the direction an ion moves across a membrane is determined by the electrochemical gradient.

What evidence supports the LAW OF CONSERVATION OF ENERGY?
1. Mechanical energy is converted to chemical energy during photosynthesis
2. Energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis
3. Oxygen is made from the breakdown of carbon dioxide during photosynthesis
4. The sun gives off light energy that is absorbed by plants

Answers

The evidence that supports the law of conservation of energy is as follows: mechanical energy is converted to chemical energy during photosynthesis.

LAW OF CONSERVATION OF ENERGY:The law of conservation of energy states that energy can neither be created nor destroyed but is changed from one form to another.

This means that energy involved in chemical reactions and natural phenomena is recycled by transformation and doesn't get destroyed.

A typical example that obeys this law is photosynthesis, which converts mechanical energy in sugar molecules to chemical energy in ATP.

How are the enzymes that nerve cells produce different from the enzymes that blood cells produce? A. The molecules that nerve cells digest are more complex than those digested by blood cells. B. The genes that are activated in nerve cells are different from those activated in blood cells. C. Nerve cells contain more ribosomes than blood cells. D. Nerve cells contain more mitochondria than blood cells.

Answers

Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.
