What type of inheritance results when the phenotype of a heterozygote is intermediate between both homozygotes?.

Round worms lack a complete circulatory system, whereas segmented worms do. The circulatory system of a segmented worm includes blood, the heart, the capillary system, and hemoglobin.

Flatworms have a ribbon-like body with no cavity. Roundworms are worms with a body cavity but no segments. Segmented worms have a body cavity as well as segmented bodies.

The Annelida consist of segmented worms. They lack legs and a hard skeleton. Unlike mollusks, the bodies of annelids are divided into many small segments, similar to rings joined together.

The earthworm can move more easily if it is segmented. Setae are muscles and bristles found in each segment or section. When moving through soil, the bristles or setae help anchor and control the worm. The bristles secure a section of the worm to the ground while the rest of the body protrudes forward.

The enzyme that hydrogen ions flow through to make ATP is ATP synthase.

What is the process of oxidative phosphorylation?

During chemiosmosis, hydrogen ions are pumped across the membrane by a sequence of processes that make up the electron transport chain, creating an electrochemical gradient.

Only a membrane protein known as ATP synthase allows hydrogen ions in the matrix space to pass through the inner mitochondrial membrane.

ADP is converted into ATP by ATP synthase as protons pass through.

Oxidative phosphorylation describes the process by which ATP is produced in mitochondria by chemiosmosis.

What is ATP synthase?

Adenosine triphosphate, an energy storage molecule, is made from adenosine diphosphate and inorganic phosphate by the enzyme ATP synthase. As it modifies ADP by forming a P-O bond, it is categorized as a ligase. A molecular device is called ATP synthase.

Hence, ATP synthase is the enzyme that hydrogen ions flows through to make ATP

The difference about the ends of restriction enzymes is that the HaeIII produces a blunt end when cut whereas MaeI and CfoI produce sticky ends when cut by the enzyme.

Restriction enzymes also have another name called molecular scissors. These are the enzymes that cut the continuous strand of DNA by producing a nick at the phosphodiester bond of the backbone. These are divided into two categories: exonucleases and endonucleases.

Sticky ends are the region produced by the cut through restriction enzymes. In this both the strands of DNA are cut at separate places and therefore one strand remains longer than the other strand.

False, plants also store energy and exhibit respiration and plants use this stored energy to function.

Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration. The pea pod used sunlight energy to build sugar molecules with the help of carbon dioxide and water. When the rabbit ate the pea pod, it received energy from the sun that was stored in the plant's sugar molecules.

A species of mouse which was once killed by a certain disease is now resistant to the disease because some individual mice that were resistant to the disease survived and reproduced offspring. Those that weren't resistant died. Thus, the correct option is D.

Resistant genes is the gene which contains the information for the production of a protein that makes an antibiotic ineffective on that organism and hence confers resistance against that antibiotic to a pathogen.

The transfer of resistant genes can occur in organisms. Acquired resistance from the parents can occur through horizontal transfer of genes between the bacterial species, or by vertical transmission that can occur between mother and offspring at birth and during lactation period, or spontaneously due to the exposure to an antibiotic. These genes help the organism to survive in the antibiotic medium and produce offspring.

Answer:

The three episodes that occur during the photosynthesis cycle are: Light energy is absorbed by chlorophyll, which breaks down water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. The reduction of carbon dioxide leads to the formation of carbohydrates.

Answer:

solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose

Explanation:

Left ventricle (LV) of the heart pumps oxygenated blood to the head and body and right atrium (RA) receives deoxygenated blood from the head and body and left atrium (LA) receives oxygenated blood from the lungs.

To obtain oxygen, the circulatory system (cardiovascular system) pumps blood from the heart to the lungs. The heart then sends oxygenated blood to the rest of the body via arteries. The veins return oxygen-depleted blood to the heart to restart the circulation process.

Arteries transport blood away from the heart, while veins transport blood back to the heart. The circulatory system transports oxygen, nutrients, and hormones to cells while also removing waste products such as carbon dioxide.

The heart is divided into four chambers: two upper chambers known as the left and right atriums, and two lower chambers known as the left and right ventricles. It also has four valves: the tricuspid, pulmonary, mitral, and aortic.

A high osmolarity is produced by the urea recycling, which confines the majority of the urea in the medulla and aids in water absorption.

Urea molecules are carried by the blood as it enters the glomerulus; these molecules are subsequently filtered by Bowman's capsule before entering the proximal convoluted tubules. The Henle's loop receives the reabsorbed portion of the entering urea. The medulla of the kidney secretes urea into the lumen of the tubules in the form of a loop, bringing the concentration of urea to 100%.

From the loop, 100% of the urea enters the distal convolved tubules (DCT). Thirty percent of the substance in distal convoluted tubules is reabsorbed to the cortex, while the remaining seventy percent enters collecting tubules. In the medulla, fifty percent is being reabsorbed. The remaining 5% is reabsorbed by the arteries and vasa recta, which are connected to the nephron, while 15% is discharged as urine.

On the other hand, deeper (confined) aquifers are less likely to follow surface features and have watersheds (or basins) that are governed by geologic reasons. Thus, option C is correct.

In general, surface aquifers (the water table) resemble surface-water watersheds, and their flow typically does not cross borders at the surface.

Due to the fact that groundwater flows from high points (where it divides) to low places, groundwater watersheds conceptually are comparable to surface-water watersheds (outlets, discharge areas).

If the element has a half-life of 30 years, the time it takes only until 1 percent of the element remains is around 199.3 years.

Half-life is the time taken for an unstable isotope to decay into half of its original value.

Given that:

      N = N0 (1/2)^h

N/N0 = (1/2)^h

N/N0 = 1/100 (since N is 1% of N0), so

       1/100 = (1/2)^h

log (1/100) = hlog(1/2)

             h = log(1/100) / log(1/2)

                = log(100)/log(2)

The statement that best describes cell division in plant and animal cells is that cytokinesis occurs by formation of a cleavage furrow in animal cells, but not plant cells, which means that option A is correct answer.

Cell division is defined as the process in which cells of the organisms divide into daughter nuclei, in order for the multiplication of organism and sustainability of life. There are generally two types of cell division namely Mitosis and Meiosis. Mitosis is the process in which cell duplicates its chromosomal material and then divides it into two daughter nuclei. Meiosis on the other hand involves formation of eggs and sperm cells. Cytokinesis is defined as the method of division of cytoplasm due to which the genetic material and other organelles get divided into daughter cells. In plant cells, cell plate is formed during cytokinesis and in animal cell, cleavage furrow is formed and it deepens until daughter cells split from parent.
