DIFFUSION THROUGH CANALICULI.
Explanation:
Through the process of diffusion through the canaliculi, nutrients are delivered to compact bone. Osteocyte communication occurs through microscopic channels called canaliculi that exist between lacunae.

They have a defect of their "curly gene," that's on the second chromosome. Having curled wings is a dominant mutation, this means that only one copy of the gene must be altered to supply the disorder. In reality, if both copies are mutated, the flies do not continue to exist.
Geneticists have lengthily counseled that mutations in insect pigment genes reason for modifications in the fly's brain because these pigments are crafted from dopamine, a chemical messenger that acts in the brain.

_____ is a gene silencing technique that is based on the fact that RNA molecules can fold into short, double-stranded regions where the base sequence is complementary.
RNAi is a gene silencing technique that is based on the fact that RNA molecules can fold into short, double-stranded regions where the base sequence is complementary.
What is the RNAi mechanism?A conserved biological response to double-stranded RNA, known as RNA interference (RNAi) or post-transcriptional gene silencing (PTGS), promotes resistance to both endogenous parasites and exogenous harmful nucleic acids and controls the expression of protein-coding genes. Small double-stranded RNA (dsRNA) molecules are used as triggers by most eukaryotic cells' RNA interference (RNAi) regulatory mechanisms to direct homology-dependent control of gene activity.
In order to protect plants from molecular parasites like viruses, RNA silencing has evolved. In controlling gene expression for growth and development, it is also helpful. These pathways interact with one another and generate short RNAs to function.

Explain why Mendel needed to study two different genes rather than two different alleles of one gene in order to derive the principle of independent assortment.
Mendel needed to study two different genes rather than two different alleles of one gene to derive the principle of independent assortment because independent assortment is the phenomenon of the segregation of alleles of two or more genes during gamete formation independent of one another.
When Mendel studied the inheritance of two genes he observed that the alleles of these two genes were assorted during gamete formation in a random fashion and were not dependent on each other. He stated this as the law of independent assortment.
The independent assortment of genes is possible because of the random arrangement of homologous chromosomes at the metaphase plate during meiosis-I.

Learning to duck after you get slapped in the face is a form of conditioning.
ConditioningAccording to the "learning" or conditioning theory of behavioral psychology, a person or an animal's response to an object or event can be changed. Operant Conditioning, which Skinner developed from the most well-known variation of this, is a result of the Classical Conditioning method. The experiments of Ivan Pavlov, who decided to study conditioning after learning that his canine subjects began to salivate not only when meat powder was presented to them, but more importantly, when the person who was feeding them came into proximity with them, provided evidence for this mode of learning. The dogs unintentionally learned through classical conditioning to link the person giving them food with the meal itself and responded similarly to the feeders as a result.

Explain how warm atmospheric conditions lead to severe storms.
The warm atmospheric conditions lead to severe storms is Thunderstorms
Layers of warm, moist air rise in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form. At that location, the updraft's moisture condenses to create imposing cumulonimbus clouds and, eventually, precipitation.
Thunderstorm development requires three basic components: moisture, an unstable atmosphere, and a method to get the atmosphere moving. To create thunderstorm clouds and precipitation, moisture is required.
The warm air cools and condenses as it ascends, generating tiny water droplets. When there is sufficient instability in the atmosphere, warm air rises swiftly, and the water vapor condenses quickly to form cumulonimbus clouds. Usually, it takes less than an hour for these cumulonimbus clouds to form.

The correct order of structures in the nervous system pathway to hearing is that axons project to the auditory cortex.
A. Axons project to the auditory cortex.Inferior colliculus neurons send their axons to the medial geniculate nucleus (MGN) of the thalamus, which in turn projects to the auditory cortex.
What is the route of the roads?
The cochlear nerve passes through the internal acoustic meatus in the temporal bone and enters the brainstem in the upper part of the medulla, at its junction with the pons, next to the facial nerve (VII), in the region of the cerebellopontine angle.
Which part of the brain controls hearing?Temporal Lobe: located near the ear, it is responsible for the perception of hearing, enabling the analysis of sounds. In addition, it functions as a processor of memory and emotions.
With this information, we can conclude that We hear when sound waves travel through the air to our eardrum and then through the middle ear to our inner ear and from there finally to the auditory centers of our brain. Our ears are always active, continually transporting sounds along this auditory pathway.

What are mutations?
For biology revision
Answer: cells are incredibly accurate when they are copying DNA, but there are going to be some errors.
Most of these errors can often times break the organism in some way or might not at all.
But every now and then, some of these errors either as an individual base pair or maybe cumulatively can produce a different phenotype and potentially a phenotype that has an advantage.
This is mutation.
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
what are the different types of mutation?There are three types of DNA Mutations:
base substitutionsdeletions insertions.Base substitutions : Point mutations are single nucleotide substitutions; consider the point mutation Glu ——-> Val is the culprit of sickle cell anaemia.
Deletions : A deletion happens when one or more base pairs are deleted from the DNA, which causes a frameshift.
Insertions: Depending on whether multiples of three base pairs are entered, the addition of additional base pairs may cause frameshifts.

Durairajanayagam D, Agarwal A, Ong C. Causes, effects and molecular mechanisms of testicular heat stress. Reproductive biomedicine online. 2015 Jan 1;30(1):14-27.
Temperature affects spermatogenesis, which functions best at body temperatures just a little lower than those.
Abstract:To keep testicular temperatures below those of the body core, adequate thermoregulation is essential. The process of mammalian spermatogenesis and the resulting spermatozoa are negatively impacted by elevated testicular temperature. Therefore, sperm quality can be affected and the likelihood of infertility is increased by thermoregulatory dysfunction resulting in heat stress. This article reviews a variety of internal and external factors that may lead to testicular heat stress. We go into more detail on how heat stress affects the spermatogenesis process, the resulting epididymal spermatozoa, germ cells, and the alterations that result in the testis.
We also go over the chemical reactions of germ cells to heat exposure and potential processes, such as apoptosis, DNA damage, and autophagy, that could lead to heat-induced germ cell damage. Further explanation is provided for the intrinsic and extrinsic processes involved in the complex mechanism of germ cell death. These intricate apoptotic pathways ultimately result in the demise of germ cells.
