Answer:
Both organs exchange oxygen and carbon dioxide.
Explanation:
This is because the plant leaf exchange gases during photosynthesis where it uses carbondioxide and water in the presence of light energy and chlorophyll to produce carbohydrates and oxygen. Therefore oxygen is given out to the atmosphere and carbondioxide is taken in.
The lungs also is an organ of respiration, it is where exchange of gases take place where oxygen is taken in through breathing and carbondioxide is given out as by product.

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.

The atom of sodium has one valence electron. To form a bond, the sodium atom should
Answer:
Loose that one electron
Explanation:
Sodium is a member of group 1 in the periodic table. The members of this group are known to form a univalent positive ion and are highly electropositive.
They give out one electron and go into electrovalent of ionic combination.
Hence, for sodium to form a bond, it looses the only electron in its outermost shell.
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.

Answer:Body, Trace, and Chemical Bones
Explanation:
Fossils are remains of ancients organisms that are preserved. They are usually in rock form. This remain could be compressed after the decay of other body part, it indicates the existence of a particular organism at a time.
Fossil can be Body fossils : this include body structures suck as teeth, hand or any other body part that is not decayed.
Trace fossils are rock materials or substance that indicated the existence of an organism and Chemical Bones - Bones are specialized body structure, it also helps identify an organism existence and for record.

G G A---T A G---C C G---T T A Find the mRNA strand. *
Answer:
CCU-----AUC----GGC-----AAU
Explanation:
This question is describing the process of transcription, which is the process by which a DNA strand is used as template to synthesize a mRNA strand or molecule. This synthesis in transcription, which is carried out by an enzymes called RNA polymerase, is based on the COMPLEMENTARY BASE PAIRING RULE.
Complementary base pairing rule states that Adenine base will always hydrogen pair with Thymine while Guanine will always pair with Cytosine. However, Uracil base (U) replaces Thymine (T) in RNA. Hence, the pairing is as follows: A-U, T-A, G-C etc.
Based on the above, a DNA strand containing the following sequence: G G A---T A G---C C G---T T A will be transcribed into the following sequence of mRNA: CCU----AUC----GGC----AAU.
Why was the discovery of DNA important to our daily lives?

Phenotype is the PHyiscal trait e.g height, eye colour and blood type.
Genotype is the GENE of the trait or the alleles. E.g height; tall is T, short is t. these are the alleles that could make up the height.

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.

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.

Scientists use many resources to piece together the history of life on Earth. 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.
