In the transcription process, segments of DNA serve as templates to produce what kind of base sequences in RNA molecules?
A. complementary
B. identical
C. opposite
D. random
Answer:
A.
Explanation:
I don't have an explanation
In the transcription process, segments of DNA serve as templates to produce complementary RNA molecules.
Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G). Different types of RNA exist in cells: messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA). In addition, some RNAs are involved in regulating gene expression. Certain viruses use RNA as their genomic material.
Ribonucleic acid, or RNA. I often think of RNA as being the less well-known cousin of DNA, particularly for people outside the field of biology or genomics. But really, when you think about it, RNA, in so many ways, is the actual functional form of nucleic acids that really the body uses to do the business of, you know, constructing cells or responding to immune challenges, of carrying amino acids from one part of the cell to the other, that quite often I feel that RNA doesn't get the respect it deserves. So what I think we can share is that the different forms of RNA -- mRNA, tRNA, rRNA -- each in their own way have absolutely fundamental functions without which the biology of the genome could not be translated into practice.

6. The first trial of a controlled experiment allows a scientist to isolate and test
(1) a logical conclusion (2) a variety of information
(3) a single variable (4) several variables
Answer:
(3) a single variable
Explanation:
A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Controlled variable refers to anything or quantity such as group, person, event, etc., that is held constant by the researcher during an experiment and as such is limited.
The first trial of a controlled experiment allows a scientist to isolate and test a single variable.
Generally, most scientific experiments usually have a control group so as to avail scientists (experimentalists) an ability to compare the outcome of their test results before testing a single variable. This control group is not given the treatment or influenced by the same single (independent) variable as the experimental group.
Therefore, this is the reason why science completely or totally rejects any hypothesis which is not supported by observations, as well as the results obtained from control experiments.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

(is there a way to tell, is it like relative dating?)
Answer:
within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt.
Explanation:
Fossils within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt.
What do you mean by fossils?Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers.
A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber.
Fossils are the geologically altered remains of a once-living organism and/or its behaviour. There are two main types: body fossils represent all or part of the organism's body.

What do you mean by predators?Predators are organisms that hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey. Predators can be carnivores and omnivores. Lions, tigers, sharks, and snakes, all are predators.
Moreover, the best-known examples of predation involve carnivorous interactions, in which one animal consumes another. Think of wolves hunting moose, owls hunting mice, or shrews hunting worms and insects.
Therefore, predators are wild animals that hunt, or prey on, other animals. All animals need food to live. Predator animals need the flesh of the animals that they kill to survive. Weasels, hawks, wolves, mountain lions, and grizzly bears are all predators.

How are bat forelimbs different from other mammals' forelimbs?
A: There are more bones.
B: The bones in the digits are longer.
C: Bats lack a thumb.
D: The wrist is more mobile.
Answer:
D
Explanation:
DDDDDDDDDDDDDDDDDDDDDDDDDDD
The forelimbs of bats are different from other mammals' forelimbs because the bat's wrist is more mobile. Therefore, option D is correct.
What are the functions of the forelimbs of bats?Tetrapod forelimbs are converted into bat wings. As mammals, bats have skeletal components in their wings that are morphologically similar to those in other tetrapod forelimbs. The primary function of the forelimbs of bats is to help them fly.
Wings are modified forelimbs. Skeletal changes enable muscle attachment and changed limb bones that can form wings to aid in aerial mobility. During the flight, the tail stabilizes and controls motions. The robust and well-developed muscles enable the beating of wings.
The forelimbs of bats are different from other mammals' forelimbs because the bat's wrist is more mobile. Therefore, option D is correct.

Conduct online research on the classes of soil remediation: in-situ and ex-situ. Briefly describe your findings.
Answer:
(Answers may vary.)
There are two classes of soil remediation: in-situ and ex-situ.
In in-situ remediation, there is no excavation of the contaminated soil. This remediation is an economical way of cleaning up. However, it takes a long time for the treatment to be effective. In addition, the treatment is not uniform because of variability within soil and difficulty in monitoring remediation progress.
Ex-situ remediation involves excavating a contaminated area. In this method, the soil is either treated on the same site or transported to a remote site for cleaning. This type of remediation is complex and expensive, but very effective. It involves the following:
homogenization of the contaminated soil before treatment
monitoring to ensure that the soil is cleaned to the required level
Explanation:
Soil remediation is the process of making the soil pure and free of contamination which affect the health of the soil and the organisms that depend on it for their survival.
The two classes of soil remediation are:
In-situEx-situ
In-situ has to do with the treatment of the soil by removing the affected soil so that other parts of the soil does not get contaminated.
Ex-situ method is the process which involves taking the affected soil to an external site for decontamination which ensures that the other parts are not affected.

The fossil record is one source of information that can help scientists understand the way life on Earth has changed over millions of years. What does the fossil record tell us about the history of different species on Earth?
Answer:
See explanation
Explanation:
Fossil records contain an extensive detail of the evolution of various species on earth which have been preserved in the remains of these organisms or imprints that organisms that existed long ago must have left in sedimentary rocks.
Fossil records basically tell us about the past. They tell us about the species that once existed on earth. They also tell us how long these species existed and how the were related to other species.
This information help us to work out how these organisms lived and the environment where they lived.
