Answer:

B. the energy production in the sun.

Explanation:

The sun ngenerates its energy by nuclear fusion of hydrogen nuclei into helium.

The right answer to the provided question is that the sun's energy generation method is based on fusion.

Nuclear fusion is the process that occurs when two or more atomic nuclei unite to generate one or more distinct atomic nuclei and subatomic particles neutrons or protons.

The mass differential between reactants and products results in either energy release or absorption.

In the Sun's core, hydrogen is being converted into helium. This is referred to as nuclear fusion.

The fusion of four hydrogen atoms produces one helium atom. During the process, some of the mass is converted into energy.

So, we can conclude that Nuclear fusion occurs within the sun's core. Because of the amount of pressure within the sun, nuclear fusion occurs at its core.

Answer: See attached picture.

Explanation:

DNA or deoxyribonucleic acid is the name for the molecule that contains the genetic information in all living things. This molecule consists of two strands that wind around each other to form a double helix structure.

The basic unit of nucleic acids are called nucleotides, which are organic molecules formed by the covalent bonding of a nucleoside (a pentose which is a type of sugar and a nitrogenous base) and a phosphate group. So each nucleotide is made up of a pentose sugar called deoxyribose, a nitrogenous base which can be adenine (A), thymine (T), cytosine (C) or guanine (G) and a phosphate group.

What distinguishes one polynucleotide from another is the nitrogenous base, and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information, following the following criterion of complementarity: A-T and G-C. So the sequence of these bases along the chain is what encodes the instructions for forming proteins and RNA molecules. In living organisms, DNA occurs as a double strand of nucleotides, in which the two strands are linked together by connections called hydrogen bridges.

The chemical convention of naming the carbon atoms in the pentose nucleotide pentose numerically confers the names 5' end and 3' end ("five prime end" and "three prime end" respectively). The 5'-end designates the end of a DNA strand that coincides with the phosphate group of the fifth carbon of the respective terminal deoxyribose. A phosphate group attached to the 5'-end allows the ligation of two nucleotides; for example, the covalent bonding of the 5'-phosphate group to the 3'-hydroxyl group of another nucleotide, to form a phosphodiester bond.

Answer:

One allows microbe to move in the medium and the other allows to see it.

Explanation:

Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.

Complete question:

Question 49 (1 point) The following questions refer to the description below. You have read that soapberry bugs, Jadera haematoloma, adapt to available food sources. For example, in southern Florida, soapberry bugs feed on seeds of a native plant, the balloon vine. In central Florida, the balloon vine is rare and soapberry bugs have switched to eating seeds of an introduced species, the golden rain tree. The seeds of the golden rain tree fruits are much closer to the fruit surface than the seeds of the native balloon vine fruit. As a result, natural selection results in beaks that are shorter in soapberry bugs that utilize golden rain tree fruits than those that feed on balloon vine fruit seeds.

What type of natural selection do you think is acting on these bugs if we consider the golden rain tree bugs and balloon vines bugs together as one group?

Solution:

Photosynthesis is a process by which green plants and vegetables prepare their food using carbon dioxide from the atmosphere, water from the soil and in the presence of sun light with the help of chlorophyll.

-- During photosynthesis process, electrons are originated from the chlorophyll and it absorbs the photons of light from the atmosphere.

-- the energies are passed inward from the pigments to pigments until they reaches the reaction center.

-- then the energy is transferred to the P680, thus boosting the electron to the high energy level.

-- this high energy electron then passes to the acceptor molecule and is replaced with the electron from the water.

-- this splitting the water releases oxygen in the atmosphere that we breathe.

-- the electron generation is proportional to the DPIP reduction light transmittance.

-- the decrease in the light availability decreases the electron quantity of the electrons which will be generated.

-- the boiling disrupts the functional structures.

Answer:

Calcium is an essential ion as it required in the contraction of both cardiac and skeletal muscles. The sarcoplasmic reticulum stores these ions that are pumped by calcium pumps and released when contraction and functioning of these muscles. It binds to troponin and altered the change of shape and prevents tropomyosin from the site of the binding.

In case of cardiac muscle, the coupling Ca2+ is from its contact with extracellular concentration of Ca2+. When the calcium is released in the skeletal muscle it leads to the interaction between the actin and myosin. The binding sites of the myosin is exposed that bind and forms cross bridges with actin and hence helps in the contraction of the muscle. With the calcium induced calcium release, it helps in the contraction of the cardiac muscle. As the calcium is released it leads to initiation of the smooth muscle contraction in the cardiac muscle through binding of calmodulin and leads to activation of the myosin light chain kinase enzyme. There are receptors for the Calcium induced calcium release within the cardiac cells called as cardiomyocyte that binds to the calcium during depolarization and hence releases more calcium ions within the cells.

Answer:

Trachea

Explanation:

The laryngeal reflex occurs and it is present in babies after birth. When water occupies or enters the mouth, the laryngeal reaction is triggered. While your infant is underwater, the glottis and epiglottis shut, keeping water from penetrating the throat(larynx and pharynx) and establishing a watertight barrier to the lungs. This is so to prevent the aspiration of water into the lungs.

Answer:

Due to conjugation.

Explanation:

Bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells because of conjugation process. Conjugation is a process by which one bacterium transfers its genetic material or genes to another bacterium or cell through direct contact with it. During conjugation, the bacterial cells serves as the donor of the genetic material, and the eukaryotic cell serves as the recipient that receives the genes.

So, we know that a metamorphic rock is either an igneous or a sedimentary rock that are exposed to intense heat and pressure.

But when the metamorphic rock is thrusted deep underground through subduction, it will again be subjected to intense heat. This can cause it to melt, turning it into a magma. When the magma cools down, it again becomes an igneous rock and the rock cycle continues.

Explanation:

A) Biodiversity is simply known as the number and variety of organisms found in a definite environment or region.  Scientists have devised several ways of measuring biodiversity and the methods to be used depend on the type of organisms they are to count.  

Canopy fogging – one of the ways of measuring biodiversity, has remained an effective way of obtaining details about the biodiversity of insects.  It involves the act of spraying  low dose of insecticides on a tree top, and when the insects fall from the trees, they are being collected on a large screen, that looks like a funnel.  

Transact sampling is another way of measuring biodiversity and this time, with a transact line. The transact line is usually a measuring tape or rope that has been marked at set intervals.

b) Ecosystem stability is the ability of the ecosystem to maintain its steady state, even after it has experienced stress or disturbances.  The biodiversity of an environment makes huge impact on the ecosystem stability in that particular area. It has been known that certain areas that have high levels of species and genetic diversity, are more likely going to an ecosystem that is complex, with varying food webs and biotic interactions. The increase in this complexity makes it more likely that the ecosystem of that area will rightly move back to a stable state whenever disturbances are experienced.

There are evaluated scientific evidence that shows that reduced biodiversity affects the transmission of communicable disease in agricultural crops, animals and humans. Loss of biodiversity usually increases susceptibility to diseases in plants and humans.  

The product of the reproductive processes of an animal or plant : young, progeny The disease can be transmitted from parent to offspring. b : child a mother of numerous offspring.
