Maize reproduces sexually while rhizopus reproduces both sexually and asexually.

Rhizopus belongs to a group of organisms in the kingdom Fungi. Maize, on the other hand, belongs to a group of organisms in the kingdom Plantae.

Rhizopus is able to reproduce both sexually and asexually. Sexual reproduction is by the fusion of compatible hyphae - one carrying the + strain and the other the - strain.

Asexual reproduction in rhizopus is by the formation of asexual spores - sporangiospores and chlamydospores.

Maize is only able to reproduce sexually. The male gamete in the form of pollen pollinates (fertilizes) the female gamete in the form of ovule or egg. Double fertilization occurs to form a seed coat that nourishes the zygote.

Renin is secreted in response to a significant drop in blood pressure or blood volume.

The juxtaglomerular apparatus secrete renin, and as specialized smooth muscle cells surrounding the afferent arteriole also have the capacity to affect the perfusion of the glomerulus.

The main function of the Juxtaglomerular apparatus is to secrete Erythropoietin and Renin.

The juxtaglomerular apparatus functions to maintain blood pressure and to act as a quality control mechanism to ensure proper glomerular flow rate and efficient sodium reabsorption. The urethra extends from the bladder to the surface of the body.

Baroreceptors found in the arterioles trigger renin secretion if there is a fall in blood pressure in the arterioles. Activation of the sympathetic nervous system can also stimulate renin release through activation of beta-1 receptors.

Numerous antiepileptic medications, such phenytoin, have been designed to block voltage-gated sodium channels (VGSC) in neuronal membrane. In addition, multiple toxins and pharmacological modulators work by attaching to various biophysical states of the VGSC to cause their effects.  Depending on how modulatory agents act, some VGSC states are stabilized or destabilized, altering the channel's biophysical properties. The first anticonvulsant to successfully treat epileptic disorders without causing undesirable side effects such as brain drowsiness was phenytoin.

Phenytoin has been indicated to block high-frequency neuronal activity potentials from the inner vestibule of the pore, as demonstrated by electrophysiological research and site-directed mutation.

Frequency and voltage both affect phenytoin binding.

There are theories that phenytoin interferes with the late sodium current that sustains depolarizations in epilepsy by blocking non-inactivated channels.

The beginning of the Green Revolution is often credited to Norman Borlaug, an American scientist with an interest in agriculture. In the 1940s he began his research in Mexico, developing new disease-resistant, high-yielding wheat varieties. The Borlaug wheat variety combined with new mechanized farming techniques allowed Mexico to produce more wheat than its population needed, and by the 1960s it was a wheat exporter. Prior to using these varieties, the country imported almost half of its wheat supply.

The relationship between the caterpillars and milkweed is characterized by - for the milkweed and + for the caterpillar

The monarch butterfly can only survive if it feeds on milkweed during its whole life cycle. Because monarch butterfly larvae, also known as caterpillars, can only feed on milkweed, this species of butterfly is also known as the "milkweed butterfly."The female monarch butterfly lay her eggs on the bottom of the milkweed leaves, which will offer the developing larvae protection as they grow. The big leaves function similarly to umbrellas, protecting the eggs from the excessive heat of the summer sun and providing cover from the heavy downpours. In addition, the leaves provide a wonderful place to conceal oneself from any predators that might be interested in eating the eggs before the larva hatches. As soon as the eggs hatch, the larvae will begin to feed on the leaves of the milkweed plants. For the first few days of their lives, they will consume food continuously, day and night. The milkweed provides the young caterpillars with more than just food while they develop. Milkweed offers a one-of-a-kind defence against predators to both the monarch butterfly larvae and the adult butterflies. The larvae consume a significant proportion of the milkweed plant's dangerous compounds since the milkweed plant itself contains poisonous elements. As a result, the monarch butterfly themselves become poisonous.

when changes in a protein appear to accumulate at a constant rate over time is called option (c) i.e, Molecular clock.

The term "molecular clock" refers to a method that estimates the time in prehistory when two or more life forms diverged by analyzing the mutation rate of biomolecules. Typically, nucleotide sequences for DNA, RNA, or amino acid sequences for proteins serve as the biomolecular data for these calculations.

Hedges, a biology professor at Penn State, claims that the molecular clock counts the mutations that accumulate through time in the gene sequences of various species rather than counting seconds, minutes, and hours.

Mutation and recombination, the two fundamental biological processes that give rise to all heritable variations, are the foundation of molecular clocks. Mutations are modifications to the genetic code of DNA, for as when the nucleotide Guanine (G) turns to Thymine (T).

Answer: Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker. By contrast, an individual who is homozygous for a marker has identical versions of that marker.

Organisms can be homozygous or heterozygous for a gene. Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous. People with CF are homozygous recessive. Since Huntington's disease is autosomal dominant, people with the disease can be either homozygous dominant or heterozygous.

Dendrites of the postsynaptic neurons are the structures that receive chemical messages -neurotransmitters- from the presynaptic neurons. The correct option is D. Dendrites.

Neurons are cells that communicate with each other through the transmition of nervous impulses.

Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.

Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.

During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.

The neurotransmitter is a molecule that travels through the synaptic space forward to the dendrites of the other neuron or to the effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.

This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.

Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.

According to this framework, when two neurons communicate, the neurotransmitter released by one of them reaches the receptors located in the dendrites of the postsynaptic cell.

Dendrites are the structures that receive chemical messages from the other cells.

The correct option is D. Dendrites.

It is an example of Fixed Action Patterns.

A fixed action pattern (FAP) is a predetermined set of behaviors that happen in a predetermined order in response to a sign stimulus, which is an external stimulus. The behavior is "fixed" because it is essentially unchanging and behaves consistently among members of a species.

FAPs are inherent, which means that the animal is born with the capacity to engage in the behavior and does not require learning. FAPs are also typically finished after being triggered. The ability to instinctively identify and attack prey or, as in the case of sticklebacks, the ability to produce more young that can survive to adulthood are just two examples of how these behaviors may be crucial to improving an animal's fitness.
