Which process cycles carbon through the
atmosphere?
Answer:
In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals.
Explanation:
Why is the presence of organic material in the soil important?
A)
It wards away plant eating organisms.
B)
It increases plant growth.

Which of the following is an abiotic limiting factor for a plant population in an ecosystem?
Invasive weed species
Animals pollinating flowers
Availability of soil minerals
Disease-causing fungal spores
Answer:
Availability of soil minerals
Explanation:
Abiotic factors are the non-living factors in the ecosystem. These materials are the chemical and physical components of the ecosystem. They are not biological in nature.
Soil minerals are abiotic since they are produced from rocks. Invasive weed species, animals pollinating and disease causing fungal spores are all biotic. They stem from biological processes.Answer:
Availability of soil minerals

2. The experiment proceeded as normal, with the experimental group hearing about the
potential presence of a gun as the confederates left the study and the control group not
hearing about the gun. All participants returned on day two for the interview with the
police detective. After debriefing, none of the participants said they were aware that the
theft was staged. The researchers found that those in the experimental group did
incorporate the gun misinformation into their memories of the theft more than those in
the control condition. That is, the mean score that a gun was present was much higher for
the experimental group (M= 67%, SD = 12.4%) than the control group (M= 33%, SD =
11.16%).

Identify all statements that accurately describe the structure of the pyruvate dehydrogenase (PDH) complex.A. A regulatory kinase and phosphatase are part of the mammalian PDH complex. B. Several copies each fo E1 and E3 surround E2. C. E2 contains three domains. D. The complex contains multiplex is made up of several copies of E1.
Answer: Options A, B ,C and E are correct
Explanation:
The structure of pyruvate dehydrogenase complex comprises if three enzymes E1, E2 and E3 which convert pyruvate to acetyl CoA. The three enzymes are have several copies.
Within the PDH complex, the E2 subunit forms the structural unit, contain three domains and are surrounded by E1 and E3. The E 2 accepts acetyl groups from E1 and transmit the group to coenzyme A. The decarboxylation of pyruvate and its conversion to acetyl-CoA by the PDH complex comes first before glucose carbon enter into the tricarboxylic acid (TCA) cycle. This process is important to the aerobic oxidation of glucose .
1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X
objective by raising the oil objective a little to avoid the damage to objective lens. Critique his
technique. (1 pt.)
Answer:
See the answer below
Explanation:
In the first instance, the 100X objective does not have any business touching the slide on the stage so that there would not be any reason to raise it a little in order to go back to a lower objective. At higher objectives, only the fine adjustment should be used to bring the object into focus so as to avoid the objective lens from touching the slide which can damage the objective and or break the slide on the stage.
For the X100 objective to be raised in order to avoid a damage to it, it means John allowed the objective to come too close to the slide in the first place. This should not have been so.

I converted from kg to g because it is the standard.
Explanation:
In leopards, being shy (S) is dominant to being sassy (s), and being timely (T) is dominant to being tardy (t).
A female leopard that is
heterozygous for both the S and I trait mates with a male leopard that is also
heterozygous for both traits. Both the S and I traits assort independently from one another.
What is the probability that they will have an offspring that is sassy and timely?
The probability that the leopards will have an offspring that is sassy and timely is 3/16
This question involves two different genes. The allele for being shy (S) is dominant to the allele for being sassy (s) in the first gene while the allele for being timely (T) is dominant to being tardy (t).According to this question, A female leopard that is heterozygous for both the S and T traits i.e. SsTt mates with a male leopard that is also heterozygous for both traits i.e. SsTtThe two heterozygous leopards (SsTt) will produce the following gametes: ST, St, sT, and stUsing these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced: S_T_ = shy, timely (9)S_tt = shy, tardy (3)ssT_ = sassy, timely (3)sstt = sassy, tardy (1)According to this question, the probability that the two leopards will have an offspring that is sassy and timely is 3/16.Learn more at: https://brainly.com/question/7320771

textWhere are nonpolar amino acids of a protein more likely to be found? Check all that apply
Answer:
At the interior side.
Explanation:
Nonpolar amino acids of a protein more likely to be found at the interior side of the soluble proteins where they are far from the water because water is a polar molecule and only polar amino acids of protein can interact with the water so that's why the polar amino acids are present on the surface of soluble proteins and the nonpolar amino acids of a protein are present at the interior side of the soluble proteins due to its nonpolar nature.
. Which of the following is used to avoid bias in a clinical trial
A) Data manipulation
B) Unfair prejudice
C) Personal interest
D) Double-blind testing
Answer:
D.
Explanation:
Whenever any clinical trail is conducted then the complete process is kept unbaised. Double blind testing can be defined as an experiment in which neither the researcher nor the person who is getting placebo and who is getting treatment knows. This is done in the clinical trials to keep the whole process unbaised.

Convoluta worms hatch in early spring. They crawl about in the mud feeding on algae, which find their way into the skin of the worms. There they prosper as they worms feed on the sun-warmed surface mud.
The worms become greener and greener as they mature. Gradually their mouths seal shut, leaving only an internal garden of algae to provide them with food. As winter approaches, their food supply is exhausted, and the worms grow pale again. They lay their eggs in the mud just before they starve to death.
How do you think both worms and algae benefit from this relationship? WHY??
