Identify all of the true statements:

A concentration gradient is the difference between
two concentrations

Active transport allows cells to transport molecules
against a concentration gradient

Diffusion results in a net overall movement from a low
concentration to a high concentration

In diffusion particles are moving around randomly in
all directions

Osmosis requires energy from respiration to be carried
out

Partially permeable membranes allow any molecules
to pass through them
​

Answers

Explanation:

a) True. The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse.

b) True. Active transport requires cellular energy to achieve this.

c) False. Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration.

d) True. For diffusion to work, the particles must be able to move around.

e) True. Osmosis requires energy from respiration to be carried

out.

f) False. Partially permeable membranes allow  only water but not other dissolved substances to pass through.

5. Which of the following correctly lists the kingdoms of life scientists currently use? (1 point) Terapoda, Aminota, Mammalia, Carnivore, Felidae kingdom, phylum, class, order, family, genus, species Bacteria, Archae, Eukarya Eubacteria, Archaebacteria, "Protista," Fungi, Plantae, Animalia Would someone please help me out with this?

Answers

The option which correctly lists the kingdoms of life that is currently being used by scientists is:  –Eubacteria, Archaebacteria, "Protista," Fungi, Plantae, Animalia– 

When Carl Linnaeus initially developed the current system of classification, he named two kingdoms, Plants and Animals. But with the use of the microscope, scientists have come to discover some new organisms. These discoveries have led to the currently used 6-kingdom system of classification.

How do enzymes speed up chemical reactions

Answers

They lower the activation energy, that is required for a specific process.

The enzyme works like a lock and key, where the lock is the enzyme that gets activated by a molecule the "key". Once they bind to each other the process gets started.

Without enzymes the process would have to occur entirely on it's own.

Answer

By lowering energy of activation of the reaction.


Explanation

High energy produced during the metabolism of reactant to product. Due to the large free energy of activation, the speeds of uncatalyzed biochemical reactions are often exceedingly slow. Enzymes lower this energy of activation so that more molecules have adequate energy to carry into the transition state to speed up the rate of reaction.

Which of the following cell organelles do both prokaryotic and eukaryotic cells have?A. Golgi apparatus

B. ribosomes

C. mitochondria

Answers

Answer:

Option B, Ribosomes

Explanation:

Ribosome exists in both free state and also as a membrane bound organelle. Thus, ribosomes is found in both the eukaryotic and prokaryotic cells as it is an essential component that facilitates the translation of RNA and formation of protein.

Golgi apparatus and mitochondria are membrane-bound organelles and all membrane-bound organelles are found in eukaryotes only. Prokaryotes do not have membrane-bound organelles

Thus, option B is correct
They both have ribosomes, so the answer is B.

In the African savanna, more wildebeests are born than the environment can support. Which is most likely to happen over a period of years as a result?A.The chances for survival of the population are reduced.

B.New food sources are discovered and become the regular diet.

C.Individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce.

D.The environment adapts by providing more resources to the growing population, increasing the chances of survival for individuals within the habitat.

Answers

In a situation where more animals are born than the environment can support , the most likely thing that will happen is that will happen over a period of years is that individuals that are well suited to the environment will reproduce while the those that have lesser adaptations will die before they reproduce. This is called the survival of the fittest. The correct option is C.

Which of the following is NOT true about energy balance? A. Energy balance is influenced by the amount of exercise one gets and their dietary habits. B. Inactive people use more energy so they should consume fewer calories. C. Stored body fat will increase if calorie intake is greater than energy used. D. Energy balance is the balance between the amount of calories consumed and the amount used for energy.

Answers

The option C, which is, Inactive people use more energy so they should consume fewer calories is not true about energy balance.  

Energy balance refers to the relationship between the energy in and energy out. Energy balance is affected by the amount of exercise one gets and their dietary habits. Stored body fat will increase if calorie intake is greater than the energy used.

Stored body fat will increase if calorie intake is greater than the energy used. Energy balance is the balance between the number of calories consumed and the amount of energy used.

The difference between the number of calories consumed and burned each day is energy balance. An inactive person uses less energy as compared to an active person due to less work out and therefore would require fewer calories.

Further Explanation:

The difference between input and output energy or calories is the energy balance of the body. The energy balance can be categorized as;

a) Perfect balance: In the energy equation if the input and output difference in energy comes out to be zero, then one has a perfect energy balance. This means neither weight is lost nor gained. During the weight loss journey, the people in their weight maintenance stage show perfect energy balance.

b) Positive energy balance: If the difference in the energy input and output results in a positive number, a person gains weight. The people like growing children, weightlifters, and pregnant women show positive energy balance and bulk up.

c) Negative energy balance: If the difference ends up in a negative number, a person achieves an imbalance required for weight loss. This is called energy deficit and the person slims down due to the negative energy difference and loss of calories.

An active person uses more of its consumed energy to perform physical activities and hence would consume more calories to keep the body at its pace. Whereas, an inactive person do little or no physical activities and therefore requires less energy. As a result, he/she would consume fewer calories due to low energy requirements.
