HELP ASAP PLS!!!! Cystic fibrosis is an inherited genetic disorder that affects the digestive system and the lungs. If a mother carries a recessive allele for a genetic disorder, such as cystic fibrosis, under what circumstances will her children inherit the disorder?
A) The children’s father must also carry the recessive allele.
B) The mother’s father must also carry the recessive allele.
C) The paternal grandfather must also carry the recessive allele.
D) The children must be female like the mother to inherit the disorder.
Answer:
A
Explanation:
For a recessive gene to affect the child they must inherit two recessive alleles because if a dominant allele is inherited than the dominant trait will be the one that is expressed in the child. The only way to get two recessive alleles is to inherit one from both parents so the father must also carry the recessive allele. This means A must be the correct answer.

Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones
to stimulate the growth of shoots.
How are gibberellins able to affect other parts of the plant?
F Gibberellins are absorbed through the stomata and attach to chloroplasts.
G Gibberellins are transported through vascular tissues to other parts of the plant.
H Gibberellins become concentrated within the tissues of the plant during mitosis.
J Gibberellins become modified once they infect healthy cells and are later released to infect
other cells.
Answer:
Gibberellins are transported through vascular tissues to other parts of the plant.
Explanation:
I just took the test.
Gibberellins are able to affect other plants through their transport through vascular tissues to other parts of the plant.
Gibberellins hormones are produced in the meristem of plants and they stimulate growth. They affect other plants through the plant's vascular system.
What is plants vascular system?Plant vascular systems are conducting tissue that helps in the transport of materials such as water, minerals, organic compounds including hormones in plants and other nutrients.
This vascular tissue allows for the movement of gibberellin to other parts of plants.Therefore, Gibberellins are able to affect other plants through their transport through vascular tissues to other parts of the plant.

Anisha's cat had a litter of 3 kittens. One of them is male, and 2 are female. Which set of symbols correctly describes the gender of the kittens? Question 1 options: XX, XX, XX XX, XY, XY XY, XX, XX Sex chromosomes do not contain X or Y
MALE - XY
FEMALE 1 - XX
FEMALE 2- XX
The correct symbols that describe the gender of a male and 2 female kittens would be XX, XX, and XY
Gender chromosomesJust like humans, male cats are generally known to be heterogametic while their females are homogametic when it comes to gender chromosomes.
The gender chromosome in male cats is XY while in the female it is XX.
Thus, a little of 3 kittens consisting of 2 females and 1 male will have the gender chromosome symbol of XX, XX, and XY.

Answer:B
Explanation:
i took it
The main objective of the given process is to translate the genetic code into a particular amino acids sequence.
What is translation in molecular biology?The given diagram signifies the process of translation, that is, the synthesis of protein. In the process, the genetic code carried from the nucleus via the process of transcription, which is producing a complementary sequence of mRNA is converted or translated.
The process of translation completes in three fundamental stages, that is,
InitiationElongationTerminationIt is terminated with ribosomes, that is, a machinery, which constructs peptide chain by combining mRNA with it. The tRNA brings the accurate amino acids to the ribosome to produce peptide chain based on the mRNA code.

A student wanted to study the amount of mold growing on pizza at different temperatures. In the experiment, the student set up four identical p and light conditions are shown in the data table below. Data Table Variables Pan 1 Pan 2 Pan 3 Pan 4 Temperature -10°C 0°C 15°C 30°C Light conditions kept in darkness kept in bright light kept in darkness kept in bright light What was one error made with the four pans of pizza when setting up this experiment? The pizzas were different sizes. The pizzas had different ingredients. The pizzas were at different temperatures. The pizzas received different amounts of light.
Answer:
The pizzas received different amounts of light.
Explanation:
In the experiment, the student sets up four identical p and light conditions, and the growth of the mold depends upon the lights falling on them, so here the error is that the different pizzas receive differing lights that affect the mold growth.
What is the significance of the mold growth on the food?Mold and bacterial growth on food indicate that it is infected, posing health risks from mild to severe. Mold can produce toxic compounds called mycotoxins, which can be harmful to human health when consumed in large quantities, as well as cause economic losses for food as it degrades.
Hence, in the experiment, the student sets up four identical p and light conditions, and the growth of the mold depends upon the lights falling on them, so here the error is that the different pizzas receive differing lights that affect the mold growth.

Explain how stem cells could be useful in both animals and plants (6 marks)
Also, how would I structure the answer, bullet points or a full written answer?
I would really appreciate it if someone could answer this.
Answer:
See the answer below
Explanation:
Stem cells could be useful in both plants and animals in that they have the capacity to replace damaged tissues or organs in the body of plants/animals.
Stem cells are actively dividing and undifferentiated cells that have the capacity to differentiate and become specialized to some specific functions. Thus, they have the capacity to replace any tissue or organ in the body of organisms, if necessary.
Without these cells, it will become difficult, if not impossible, for damaged cells of tissues or organs in the body of plants/animals to be replaced for healing purposes.
