● History of Ribosomes./ pls describe and write so facts
Answer:
Ribosomes are small dense and granular ribonucleoprotein (i.e., RNA and protein) particles found attached on the outer surfaces of endoplasmic reticulum and nucleus as well as freely scattered in cytoplasm, mitochondrial matrix and chloroplast.
Explanation:
History of Ribosomes:
Ribosomes were first isolated from E. coli by Tissieres and J. D. Watson (1958), who found that ribosomal RNA alone accounts for 22% of the total weight in rapidly growing cells (90% of total RNA). Palade (1953) was the first to observe the ribosomes as dense particles or granules in electron microscope. Upon isolation they were shown to contain approximately equal amounts of RNA and protein.
Size of Ribosomes:
There are mainly two sizes of ribosomes — (i) One is smaller prokaryotic found in bacteria and blue—green algae, having a sedimentation coefficient 70S equivalent to a molecular weight of 2.7 × 106 daltons. (Dalton is the unit of molecular weight. One Dalton is equal to the weight of one hydrogen atom), (ii) Other is of eukaryotic cells of plants and animals of 80S coefficient with a molecular weight of about 4 × 106 daltons.

Study the pedigree chart. ( picture above)
Which of these can be determined about the trait based on this chart?
○ The trait is recessive. the parents of A were both carriers
○ The trait is recessive. The parents of A were both affected
○ The trait is dominant The parents of te were both affected.
○The trait is dominant The parts of A were both carriers
Answer: The trait is recessive. the parents of A were both carriers
Explanation: The correct answer should be the trait is recessive.
Since we can only see A mothers tree and she is not affected by the trait she is a carrier.
Unfortuately, the tree does not show her father's side of the tree so we can only "assume" based on the options that he also is a carrier of the trait.
So answer it will be "The trait is recessive. the parents of A were both carriers"

what type of inheritance do two alleles have if their traits blend together?
Answer:
Explanation:
Codominance is when both dominant traits are expressed, therefore if white was considered dominant and red was also a dominant trait, the petals would have spots of white and red, with no pink. Polygenic inheritance is described by one characteristic influenced by multiple genes, which is not the case in this problem.

List 4 examples of limiting factors described in the reading and label each if it would be considered an abiotic or biotic limiting factor.
Answer:
Explanation:food, water, habitat, and mate.
Limiting factors can be either abiotic or biotic. Examples: Abiotic → water, pH, radiation, salinity. Biotic → predation, competition, parasitism.
What are biotic and abiotic factors?The ecosystem is composed of living and non-living elements that interact and depend on each other. These are the biotic and abiotic factors.
• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.
• Biotic factors are all the living components in the ecosystem.
Biotic and abiotic factors influence the survival and reproduction of living beings.
What are the limiting factors?Limiting factors are environmental conditions that act directly on populations and individuals, limiting their distribution and growth.
These factors might be either biotic or abiotic and affect natality and mortality rate, migration, etcetera.
Limiting factors might be a result of the population density or might be dense-independent.
When talking about dense-independent limiting factors we are referring to
abiotic factors, such as temperature, pH, salinity, humidity, radiation, etcetera.natural disasters like fires, volcanic eruptions, flooding, etceterahuman impactWhen talking about dense-dependent limiting factors we are referring to biotic factors and the interactions established between species that control other species' growth.
These are, for instance,
competition, parasitism, and predation
Each species carries out a different role in these interactions.
These relationships and the results are what determine the destiny of the populations and their size.
Now, since I do not have the text, I will suggest a few examples of limiting factors. Take a look at them and then look for some other examples in your reading.

Which of the four factors that affect evolution apply to the finches that the Grants studied? Use evidence from your research to support your answer.
Answer:
The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
Explanation:
Factors that affect evolution.
As per the question the evolution is a gradual process that includes the changes in the body of the organisms thereby making them more stronger and dynamic than others. The 4 features that affect evolution are mutations, natural selection, genetic drift, and gene flow.
The answer is thus are a major factor that leads to evolution in specie.
As per the case, Grants studied his works of natural selection. As per the changes associated with the environment, the large beak was an advantageous trait that was favored by natural selection. This leads to the increase in the size of the finches and the decline of other properties. Such a beak size, color, and even behavior. Hence the four-factor to consider are genetic drift, natural selection, adaptation and mutation (evolution).Learn more about the four factors.

which ventricles are divided by the septum pellucidum?
Answer:
The septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain.
Explanation:
The septum pellucidum separates the lateral ventricles. The lateral ventricles are divided into two halves by the septum pellucidum, a thin, vertical partition of tissue. It is formed of white matter and is situated in the frontal region of the brain.
The corpus callosum, a sizable bundle of nerve fibers that links the two hemispheres of the brain, is considered to have been influenced by the septum pellucidum.
The biggest ventricles in the brain are called the lateral ventricles. They are situated on each side of the brain, and cerebrospinal fluid is contained inside them (CSF). The CSF assists in removing waste from the brain and spinal cord in addition to cushioning the brain and spinal cord.

During the match, the heartbeat rate of the football fans and players increases. Explain the relationship between the heartbeat rate and the activities of the football fans and the players. (10 marks]
Answer:
Adrenaline
Explanation:
The adrenaline glands, located on top of both kidneys, are glands that produce hormones to regulate blood pressure, bodily functions, metabolisms, etc. Adrenaline is released whenever the blood is redirected towards the muscles, causing surges of energy. In general, adrenaline increases blood flow in your body, which causes the heartbeat to increase, or give the feeling of a racing heart. Between the football players and the heartbeat rate, they are getting rushes of adrenaline from either participating in the game or cheering on their team from the sidelines. Hope that made sense.

DNA is transcribed to mRNA, which then attaches to a ribosome where it is translated into a protein. The correct answer is option C.
What is the role of mRNA ?mRNA is the code of DNA that carries the information of coding proteins from the nucleus to the cytoplasm.
DNA is transcribed into mRNA where it is transcribed intro message to which kind of protein is about to be formed. A triplet forms one amino acid and this process is taking place in the ribosome.
The chain of amino acids forming a protein is released in the cytoplasm and the proteins is then assigned a particular position where so ever is them needed mostly in the cytoplasm.
Therefore, DNA is transcribed to mRNA, which then attaches to a ribosome where it is translated into a protein. The activity takes place in the ribosome.

is a grasshopper a herbivore carnivore or omnivore
Grasshoppers are well-known plant-eating insects that are herbivores.
Their typical diet consists of a variety of plant material such as grasses, leaves and plant stems. They chew and eat plant matter using their powerful jaws. Grasshoppers' digestive tracts contain symbiotic microbes that help them digest cellulose, a complex carbohydrate found in plants.
Although the primary trait of grasshoppers is herbivory, it is important to note that under certain circumstances, particularly when resources are limited, some species may engage in cannibalism. However, they are clearly classified as herbivores because of their overall diet and ecological function in the ecosystem.
