A. Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.

Answers

Answer:

This question is incomplete, the complete part is: What is the independent variable in this experiment? A) The plant species B) The amount of water that each plant gets C) The amount of time D) The different types of light the plants were put under.

The answer is D

Explanation:

In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light. Hence, the INDEPENDENT VARIABLE is the DIFFERENT TYPES OF LIGHT THE PLANT WERE PUT UNDER.

A. Carbon dioxide is inhaled and is a product of cellular respiration
B. Carbon dioxide is exhaled and is a product of cellular respiration
С. Carbon dioxide is exhaled and is a reactant of cellular respiration.
D. Cellular respiration and breathing are the same processes.

Answers

Answer:

B

Explanation:

The statement that describes the relationship between breathing and cellular respiration in animals is carbon dioxide is exhaled and is a product of cellular respiration. The correct option is B.

What is cellular respiration?

Cellular respiration is a process of breakdown of food material and releasing energy into the blood. Oxygen is mixed with the food material and carbon dioxide is released out of the body.

Breathing is a process of taking in oxygen and taking out carbon dioxide from the body. Breathing is the first step of respiration, as oxygen is needed for the respiration process, which is done by breathing.

Carbon dioxide is a product of cellular respiration, and it is taken out of the body by breathing.

Thus, the correct option is B. Carbon dioxide is exhaled and is a product of cellular respiration.

True or false: Euglena are examples of protists that can feed like an animal or use the energy of the sun to make food like a plant.

Answers

Answer:False

Explanation:

There are no man-eating plants or leaf-growing animals. The idea of an organism both photosynthesizing and hunting for food might seem strange, but this isn't science fiction. These organisms, examples of Euglena, are protists that can feed like an animal or use the energy of the sun to make food like a plant.

This statement is false. Euglena are not the examples of protists that can feed like an animal or use the energy of the sun to make food like a plant.

What are protists?

A protist is any eukaryotic organism that is not an animal, plant, or fungus. While it is likely that protists share a common ancestor, the exclusion of other eukaryotes means that protists do not form a natural group, or clade.

Moreover, protists are any member of a group of diverse eukaryotic, predominantly unicellular microscopic organisms. They may share certain morphological and physiological characteristics with animals or plants or both.

Therefore, characteristics of protists: they are eukaryotic, which means they have a nucleus. Most have mitochondria. They can be parasites. They all prefer aquatic or moist environments.

What percent of their offspring are likely to inherit the disease? if two parents carry a recessive allele for a disease but don’t have it

Answers

Answer:

1/4

Explanation:

By saying that both parents have the recessive allele, but don't have it, it tells us that both parents are Heterozygous for this trait. They have one dominant trait and one recessive trait. This is demonstrated in the in the punnett square. We can see that 1/4 of the offspring will have two recessive alleles, 1/2 of the offspring will be Heterozygous, and 1/4 of the offspring will have both dominant alleles. In order to have the disease, the offspring needs to have both recessive alleles. That is 1/4 of the the offspring.
