A student is measuring plant growth in an experiment. Using the same species of plant, he places one plant in the dark and one in artificial light. He
hypothesizes that, over time, the plant in the artificial light will grow larger than the plant in the dark. What is the dependent variable in this
experiment?
-Artificial light
-Plant growth over time
-Species of plant
-Time in light versus dark

Answer: Plant growth over time
Explanation:
i would say that because its very likely that the growth of the plant will change, the rest of them seem like a independent variable. Have a good day hope i helped.

Kangaroos are mammals that lack a placenta. Therefore, they must have an alternate way of supplying the developing embryo with
Answers
Answer: yolk sac
explanation:
the placenta does not develop for a long time so the alternate way of supplying the developing embryo is through the yolk sac which the embryo can receive nutrients and respiratory gas exchange through which the placenta will be formed later.
Kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.
What is the function of the placenta in pregnancy?The placenta is an organ that develops during pregnancy to provide nourishment to the growing fetus and to remove waste products from the baby's blood and is attached to the wall of the uterus and connected to the baby by the umbilical cord, it is responsible for producing hormones that maintain the pregnancy, such as progesterone, which helps to keep the lining of the uterus thick, also produces human placental lactogen, which helps stimulate the mother's mammary glands to produce milk.
Hence, kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.

State three things you do each day that affect the environment around you. Explain how the things you do affect the environment around you.
Answers
Answer:
Driving or using cars as a method of transportation increases the amount of Co2 released into the atmosphere. Due to this the environment becomes less and less unstable. Another daily thing I do every day that effects the environment is throwing away trash. As our trash fills the landfills some of them can be picked up by birds or even end up getting blown into the ocean. However, recycling is one positive aspect in our every day lives. When we recycle companies and factories are able to reuse things we no longer use. Because of this we are able to protect many ecosystems and the environment.
Turning lights off during the day prevents wasted energy
Recycling reduces pollution in landfills

Your answer is CLEAR CUTTING...
Explanation:
Clear cutting is when people/ industries harvest and regenerate trees areas in which all trees are cleared from a site completely...
HOPE THIS HELPS!!
Clear cutting can cause secondary succession. So, the correct option is A.
What is Secondary succession?When a place is disturbed but not severely enough to completely clear it of all vegetation and soil, secondary succession happens. Secondary succession can be started by a variety of disturbances, including fire, flooding, high winds, and human activities (such as logging of forests).
After the primary succession has indeed been disrupted as well as some animals and plants are still there, the secondary succession occurs. For the reasons listed below, the secondary succession is typically quicker than the primary succession.
There is already earth in place.The soil may still contain seeds, roots, and subsurface vegetative organs.Therefore, the correct option is A.

Which question would be asked in a dichotomous key?
A. How long are the insect's antennae?
B. Are the insect's antennae longer than its head?
C. Are the insect's antennae long or short?
D. How does the insect use its antennae?
Answers
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The statement B is correct. Are the insect’s antennae longer than its head?
What do you mean by dichotomous keys?A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.
Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.

It decreased in frequency over time.
It became extinct.
It is carried on a recessive allele.
Answers
It decreased in frequency over time.
Trait B decreased in frequency over time. So, the correct option is A.
What is trait?A trait is an attribute or characteristic of an organism that is influenced by its genes, according to genetics. Behavioural and physical characteristics, including intelligence and friendliness, can be altered by a combination of hereditary and environmental variables.
A trait is a distinctive quality or attribute that can be acquired by environmental circumstances, genetic inheritance, or both. In biology, traits are observable and quantifiable qualities of an organism, including its physical characteristics, behaviour, and other traits. For instance, physical characteristics like eye colour, height, and hair texture can all be passed on through genetics.
Hence, the correct option is A.

Which is NOT a role played by a type of RNA in protein synthesis?
O mRNA transcribes the DNA template.
rRNA makes up ribosomes, which translate the genetic code into a protein.
O tRNA pairs RNA bases with amino acids.
O pRNA is the product of chemically linked amino acids.
Answers
Answer:
pRNA is the product of chemically linked amino acids.
Explanation:
All the other choices are exactly the roles of RNA in protein synthesis: mRNA "messenger" RNA transcribes the DNA and travels out of the nucleus; then rRNA "ribosomal" RNA in the ribosome helps assemble the protein using the mRNA; tRNA "transfer" RNA brings amino acids to the assembly line of ribosome and mRNA.
There is no pRNA that I know of, although there are many types of other RNAs like piRNAs (piwi RNAs!) or siRNAs.
