A cell may transport a substance in lysosomes / vesicles if the substance is too large to cross the membrane.

Answers

Answer 1

Answer:

The correct answer would be vesicles.

Vesicles are defined as fluid filled sac or bladder enclosed by lipid bilayer.

Transport vesicles are specialized vesicles used in transportation of material (such as proteins, enzymes, hormones, neurotransmitters etc) within the cell as well as outside the cell.

Proteins required by cell organelles and plasma membrane are usually synthesized by ribosomes at rough endoplasmic reticulum and transported to Golgi bodies with the help of vesicles for further maturation and modifications.

Post-modifications these proteins are transported to their destined organelles (like plasma membrane, peroxisome, outside the cell etc) after packed into the transport vesicles.

The lipid membrane of the transport vesicle merges with the plasma membrane in order to release these proteins outside the cell.

In contrast, lysosomes are the cell organelles which contain digestive enzymes. They help in digesting food particles and unwanted cellular components or cellular debris.

Which things need to be present for natural selection to take place? (select all that apply)A.Variation in the population.
B.The ability for asexual reproduction.
C. Competition between organisms.
D. Large amounts of resources.

Answers

Answer:

A & C

Explanation:

Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

YES - A) You must have variation in the population, typically in the terms of "fitness" or having admirable/sucessful traits that make them more likely to reproduce and ensure their own offspring are fit too.

NO - B) It is sexual (not asexual) reproduction that uses natural selection for their offspring. Although some asexual organisms use natural selection, it is ALWAYS used if possible with natural selection to ensure the fitness of characteristics is passed down.

YES - C) Competition is necessary for natural selection to occur. When those who are more physically fit compete, they are more likely to live against their opponent and therefore pass on the trait of fitness.

NO - D) Although resources are necessary, large amounts are not as it does not lead to fighting over them (scarcity) bringing us back to the need for competition above.

PLEASE HELP WITH THIS ONE QUESTION What statement about the inheritance of mitochondrial DNA is true?

A) The sperm cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.

B) The egg and sperm cells contribute equal amounts of mitochondrial DNA to the zygote.

C) The egg cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.

D) The sperm cell donates most of the DNA in the nucleus to the zygote, including mitochondrial DNA.

Answers

Answer:

The answer should be C

Explanation:

The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes.

The typical sperm midpiece contains approximately 50-75 mitochondria with one copy of mtDNA in each. This represents an 8- to 10-fold decline in copy number during spermiogenesis.

A student was conducting an experiment on the growth of tomato plants. The plantsreceived the same amount of sunlight and water, but the amount fertilizer each plant
received was different. Which of the following is the dependent variable in this
experiment?
a. Amount of sunlight
b. Amount of water
c. Amount of fertilizer
d. Growth of the plants

Answers

Final answer:

The growth of the plants is the dependent variable in this experiment on tomato plants' growth. The amount of sunlight, water, and fertilizer are independent variables that were controlled and varied to observe their impact on plant growth.

Explanation:

The dependent variable in this experiment is the growth of the plants. The independent variables are the amount of sunlight, amount of water, and amount of fertilizer. By keeping the amount of sunlight and water constant, and varying the amount of fertilizer, the student can determine the effect of fertilizer on plant growth.
