The ribosome is a common cell feature between prokaryotes and eukaryotes. So the correct option is B.
What are ribosomes?The process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA and protein. The messenger RNA (mRNA) sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.
The biological machinery that produces proteins is known as a ribosome. Each cell has several ribosomes, which are each composed of two subunits. These two subunits form a tight seal around the messenger RNA molecule before moving down its length and reading each three-letter codon.
The transfer RNA, whose base sequence matches that of the messenger RNA, docks to the ribosome. A specific amino acid can be added to the end of the expanding protein chain by pairing each three-letter messenger RNA codon with the corresponding anticodon on a particular transfer RNA. Once the protein is finished, the ribosome fragments.
Therefore the correct option is B.

If the producer contains 6000 of energy how much energy will the secondary consumer contain
Secondary consumers would have roughly 60 units of energy if the producer contains 6000 units, based on the approximate 10% energy transfer between trophic levels in an ecosystem.
The question concerns the amount of energy contained by a secondary consumer if the primary producer has 6000 units of energy. In ecology, energy transfer between the trophic levels is typically about 10%. Using studies by Howard T. Odum on the Silver Springs ecosystem, we know that the primary producers generated 20,819 kcal/m²/yr. The primary consumers, in turn, generated 3368 kcal/m²/yr, secondary consumers generated 383 kcal/m2/yr, and tertiary consumers only 21 kcal/m²/yr. By applying the 10% rule, we can estimate that if primary producers have 6000 units of energy, the primary consumers would have approximately 600 units of energy, and the secondary consumers would have roughly 60 units, considering each level consumes about 90% and only passes on 10% to the next level.
What is one similarity between the lungs and capillaries?
A: They are both activated by inhalation.
B: They are both involved in gas exchanges.
C: They are both part of the circulatory system.
D: They are both regulated by the heart.
One similarity between the lungs and capillaries is that they are both involved in gas exchanges.
What do you mean by Capillaries?Capillaries may be defined as a network of blood vessels that supplies blood as well as oxygen throughout the body.
Both the lungs and the capillaries are actively involved in the exchange of gases in and out of the body. The capillaries are connected to the walls of the alveoli where oxygen and carbon dioxide diffuse. Carbon dioxide is exhaled outside by the lungs, while the oxygen is attached to the RBCs and travels to the heart.
Therefore, one similarity between the lungs and capillaries is that they are both involved in gas exchanges.

Judy kept 250 grams of juice in the freezer. What is most likely the mass of the frozen juice formed and why?
250 g, mass remains same during physical change of freezing
500 g, mass of ice is twice the mass of juice
250 g, mass is conserved when matter is destroyed to form ice
200 g, mass of frozen liquid is less than mass of the original liquid
Answer: Option A
Explanation:
The juice of 250 grams will be the same in case of ice this is because the mass of the liquid will not change when there is a physical change in the state of matter.
The change in state of matter does not changes the mass of the substance. IF 250 grams of water is kept inside the freezer to get converted into ice, then the 250 grams of liquid will be 250 grams of ice.
hence, option A is correct.
Describe the mass and surface temperature of the main sequence stars.
Answer:
Mass of main sequence star - 10 to 200 times of mass of sun
Temperature of main sequence star - 15-18 million kelvin
Explanation:
Majority of stars in the universe are main sequence stars. These stars consists of helium in their cores. Mass of main sequence stars can be as low as one tenth of mass of sun and can be as high as 150 to 200 times the mass of sun. The age of a star depends on its mass. Thus more massive a star is more is its life. The temperature of star is high enough to fuse the hydrogen with in them to form helium atom. Their temperature can be as high as 15-18 million kelvin.

Seaweed and bacteria have different cell structures How do the cellular structures of seaweed differ from that of bacteria?
A. Bacteria are made up of specialized cells.
B. Bacteria cells are larger than seaweed cells.
C. Seaweed have systems, while bacteria do not.
D. Seaweed are multicellular, while bacteria are not.
The correct answer is option D.Seaweed are multicellular and belong to the domain Eukarya, whereas bacteria are unicellular and belong to the domain Bacteria. Seaweed have eukaryotic cells with a nucleus, while bacteria have prokaryotic cells without a nucleus. Thus, the main difference is that seaweed are multicellular, while bacteria are not.
Seaweed and bacteria have distinctly different cellular structures due to their classification into different domains of life. Seaweed, which are large, multicellular algae, belong to the domain Eukarya, meaning they are composed of eukaryotic cells. These cells have a nucleus and membrane-bound organelles.
On the other hand, bacteria belong to the domain Bacteria and are made up of prokaryotic cells, which lack a nucleus and membrane-bound organelles. Additionally, bacteria are typically much smaller in size compared to the larger, multicellular seaweed.
Therefore, the correct answer to the question is: D. Seaweed are multicellular, while bacteria are not.
Which of the following body parts has smooth muscles?
Biceps
Heart
Triceps
Stomach
The stomach has smooth muscles (involuntary muscles). Therefore, option D is correct.
What are smooth muscles?Smooth muscles are also known as involuntary muscles. They are a type of muscle tissue that is found in the walls of organs, blood vessels, and other internal structures in the body.
They are called "smooth" because they lack the striations or bands that are present in skeletal and cardiac muscle tissue.
Unlike skeletal muscle, which is under voluntary control, smooth muscle is controlled involuntarily by the autonomic nervous system. This means that we cannot consciously control the contractions of smooth muscle, which happen automatically in response to various stimuli. They are responsible for many involuntary movements in the body. Therefore, option D is correct.

in humans , the allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l). a female who is homozygous for long eyelashes and a male with short eyelashes have a child. identify the phenotype and genotype ratio of the offspring.
When a homozygous female with long eyelashes (LL) and a male with short eyelashes (ll) have children, all offspring will have long eyelashes with a genotype of Ll, leading to a phenotype ratio of 100% long eyelashes and a genotype ratio of 100% heterozygous (Ll).
In humans, the allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l). A female who is homozygous for long eyelashes (LL) and a male with short eyelashes (ll) will have children. All of the offspring will have one dominant allele for long eyelashes from the mother and one recessive allele for short eyelashes from the father, resulting in a genotype of Ll for each child. Since the long eyelash allele is dominant, all of the children will exhibit the phenotype of long eyelashes. Therefore, the phenotype ratio of the offspring will be 100% long eyelashes, and the genotype ratio will be 100% heterozyous (Ll).

The incissors of a humand and a rat at a really much bigger than them of another animal. Thats why they can share the same diet.
According to the branching tree model, Jaws would most likely be located between points 1 and 2. As a result, the perch, frog, pigeon, and other species would not have developed until after the common ancestor and before the derived shared property of jaws.
How did the body of our ancestors' teeth develop throughout time?A crucial stage in the evolution of vertebrates, including humans, was the evolution of jaws in the bodies of our ancestors. Gnathostomes, the earliest jawed vertebrates, descended from jawless fish and first showed up in the fossil record about 420 million years ago.
Early jawed vertebrates were able to diversify their meals and widen their range of habitats thanks to the evolution of new feeding techniques like biting and chewing. This development also facilitated the development of more intricate teeth, which further enhanced their capacity to consume a range of food sources.
Thus, according to the branching tree model, Jaws would most likely be located between points 1 and 2.

A.) Mrs. O'Hara Gives Birth to Fourth Redhead
B.)Farmer Brown's Pigs: Best Quality Ham for the money
C.) Gene Added to Liver Improves Clotting Time
D.) Bacteria Make Human Insulin
Answer:
The correct answer is option D, Bacteria Make Human Insulin
Explanation:
Through the recombinant technology of genetic engineering, DNA of one organism can be transferred into the DNA of other organism. In a bacteria, the genes can be modified to produce human insulin. The gene for human insulin is chemically joined to the plasmid of bacterial DNA. Thus whenever the bacteria replicates its DNA, it also replicates the gene for human insulin thereby producing multiple sets of synthetic human insulin.
