Answer:
A balanced carbon cycle is essential. Carbon is a major component in carbohydrates, fats and proteins. The carbon cycle involves the exchange of carbon between living organisms (biotic) and their atmosphere (abiotic). In the carbon cycle, carbon is constantly removed from, and returned to, the environment.

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.

● 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.

All of the following occur during RNA processing EXCEPT______________A) a protective cap is added on the 5' end of the pre-mRNAB) a tail of many adenine nucleotides is added to the 3' end of the mRNAC) the exons and introns are both removed from RNA
During RNA processing, a protective cap is added to the 5' end of the pre-mRNA, a tail of many adenine nucleotides is added to the 3' end, and only introns are removed. The correct option is C.
The pre-mRNA synthesized during transcription undergoes some processing before being ready for translation. The first thing is the addition of a protective cap to the 5' end and the modification of the 3' end by the addition of a long string of adenine nucleotides.
Thereafter, the pre-mRNA is spliced to remove non-coding sequences, also known as introns. The coding sequences (exons) are joined afterwards before the mRNA is ready to be translated.

5. Blueshift is observed when

O a luminous object travels alongside an observer
O a distant luminous object travels rapidly towards an observer
O a distant luminous object travels rapidly away from an observer
O a luminous object is stationary compared to an observer
Pls help I will give 21 points if it is correct
Answer:
(b) a distant luminous object travels rapidly towards an observer.
Explanation:
Blueshift is observed when a distant luminous object travels rapidly towards an observer. The correct option is B.
What is blueshift?The displacement of an approaching celestial body's spectrum toward shorter wavelengths is known as blueshift.
When an object moves away from us, the light it emits is known as redshift; when an object moves towards us, the light it emits is known as blueshift.
The blue and red shift of stars cannot be seen with the bare eye. There are several reasons for this.
First, even for an object moving at thousands of kilometers per hour, the effect is minor, with only a slight change in hue.
Red light, with both the longest wavelength, is at one end of the spectrum.
The shortest wavelength is blue or violet light. White light is a blend of all the colors in the color spectrum. It has every color of the rainbow.
Thus, the correct option is B.

Explanation:
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.

Answer:
How would a protein transit through a cell?Explanation:
Protein cargo moves from the ER to the Golgi, is modified within the Golgi, and is then sent to various destinations in the cell, including the lysosomes and the cell surface. The Golgi processes proteins made by the endoplasmic reticulum (ER) before sending them out to the cell.

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.

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.

Explain how potential energy is affected by:
A) Mass:
B) Height:
Answer:
A. Mass
Explanation:
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
Answer:
A) Mass :
• Potential energy is directly proportional to mass, if mass increases, also potential energy increases and the reverse is true.
B) Height :
• Potential energy is directly proportional to height, if height increases, also potential energy increases and the reverse is true.
