All viruses causes diseases and are called parasites True or False
Answers
Answer:False
Explanation:All viruses do not cause diseases,instead some are very beneficial,the help to prevent infections from the plague bacteria.But some viruses cause infectious diseases like HIV/AIDS,Ebola,Corona e.t.c and viruses are not called parasites because parasites are different from bacteria or viruses because their cells share many features with human cells and some parasites only replicate within a host organism but some multiply freely in the environment.

What do prokaryotes have in common with eukaryotes?
A. They both have a Golgi apparatus.
B. They both have mitochondria.
C. They both have a nuclear membrane.
D. They both have a liquid cytoplasm.
Answers
Answer:
They both have a liquid cytoplasm.
Explanation:
A liquid cytoplasm is an essential part of a cell, in both prokaryotes and eukaryotes. It supports the internal components of the cell, and is the site of many vital cellular processes, such as glycolysis (the first part of cellular respiration).
The Golgi apparatus and the mitochondria are membrane-bound organelles that serve a specific purpose in eukaryotic cells. However, prokaryotic cells do not contain any membrane-bound organelles.
Prokaryotes do have a nucleus, like eukaryotes, but unlike in a eukaryotic cell, a prokaryotic nucleus is not surrounded by a nuclear membrane. Instead, it is just confined to a certain area of the cell, called a nucleoid.
Prokaryotes and eukaryotes both have a nuclear membrane. Option C
What is the commonality?
Prokaryotes and eukaryotes are two large categories of cells with notable variations in their organization and structure. They do, however, have some things in common.
The existence of a nuclear membrane or nuclear envelope is one of the similarities between prokaryotes (such as bacteria) and eukaryotes (such as plants, animals, fungi, and protists). The cell's genetic material, which can be either DNA or RNA, is encased in the nuclear membrane. It divides the cellular components into the nucleus and the remainder.

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.

______________________________
Rabbits can be best described as primary consumers. The correct option is b.
What are primary consumers?The 2nd trophic level is comprised of primary consumers. They are also known as herbivores. They just feed primary producers, including such plants or algae. A grasshopper, for example, is a primary consumer in the Everglades.
Primary consumers are rabbits because they are the first step up from autotrophs. Autotrophs, such as grass, are eaten by primary consumers such as rabbits.
The animals that eat the primary consumers are known as secondary consumers.
Herbivores are the primary consumers of plants. Primary consumers include caterpillars, insects, grasshoppers, termites, and hummingbirds, which only eat autotrophs (plants).
Rabbits are herbivores because they only eat plants - and herbivores are consumers because they eat plants to survive. Consumers include deer, grasshoppers, and rabbits.
Thus, the correct option is b.

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.

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.

Which of the following areas is located in the frontal lobe of the brain?
Broca's area
O hippocampus
thalamus
Wernicke's area
Answers
Answer:
Brocas area
Explanation:
Broca's area is located in the frontal lobe of the brain.
The brain region known as Broca's area is located in the left frontal lobe and is considered the nucleus that controls expressive language.
Thus, in both writing and speech, this portion of the central nervous system specializes in the production of a message with internal coherence and articulated through the language fractions.
In this area, specifically, there are capacities such as:
• Order the phonemes when making a word.
• The organization of words within a sentence.
• The semantic integration of the content to be expressed.
• Motor planning necessary for the expression of language.
Therefore, we can conclude that Broca's area located in the third gyrus in the frontal lobe is responsible for the articulation of language in any of its forms.

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.
