Mendel referred to the two types of features that the pea plants exhibited as alleles.

Mendel described the recessive trait as being hidden and the dominant trait as being obvious. When plants were allowed to self-fertilize, a small fraction of the plants exhibited the trait's previously hidden manifestation in the second generation (pollinate themselves).

The physical representation of an organism's allellic combination is called a phenotype (genotype). There are only two phenotypes that can exist in pea plants if the red allele is dominant and the white allele is recessive.

The rock appears to be rising to the surface at each side of the sub-oceanic rift valleys True.

Many rift valleys are part of “triple junctions,” a form of divergent boundary in which 3 tectonic plates meet at about one hundred twenty° angles.  fingers of the triple junction can cut up to form an entire ocean.

Rift valleys shape when tectonic plates beneath the Earth's surface diverge (or circulate far from each other in opposite directions). it's miles important to observe right here that rift valley formation, in contrast to rivers and glacial valleys, is entirely created as a result of tectonic plate motion.

Rift valleys are normally slim and long, some measuring masses of kilometers in duration. Their floors are relatively flat, owing in large elements of volcanic deposition and marine or lacustrine sedimentation. the edges of rift valleys drop steeply away within the shape of steps and terraces.

Adult lions are one of the largest members of the cat family, and their weight can vary depending on factors such as age, sex, and habitat. Adult male lions, known as "lions," typically weigh between the 330 to 550 pounds (150 to 250 kg), with some larger individuals weighing up to 600 pounds (272 kg).

Female lions, or "lionesses," are typically smaller and lighter, weighing between 265 to 400 pounds (120 to 180 kg). Lions are apex predators and are known for their strength and agility, which helps them take down prey that can be many times their own weight.

Inflammation of the membranes around the brain or spinal cord is called meningitis. It can occur in response to an infection caused by bacteria, viruses, fungi or other microorganisms, or due to non-infectious causes such as medication reactions, autoimmune diseases or cancer.

The symptoms of meningitis may include fever, headache, neck stiffness, sensitivity to light, confusion, seizures, and a rash. It can be a life-threatening condition if not treated promptly, especially in cases of bacterial meningitis. The diagnosis is typically made through a combination of physical examination, blood tests, and a lumbar puncture to obtain a sample of cerebrospinal fluid for analysis.

Treatment depends on the underlying cause of the meningitis and may include antibiotics, antiviral medication, or supportive care. In summary, meningitis is a serious condition that requires prompt medical attention and treatment.

The phenotypic difference between a person with CC genotype and one with CG is related to the ability to produce the protein erythropoietin (EPO), which is important in the production of red blood cells.

The CC genotype individuals are homozygous for the wild-type allele, which results in normal EPO production, whereas CG genotype individuals carry one copy of a variant allele that affects EPO production and function.

Individuals with the CG genotype may have a reduced ability to produce EPO, which could affect their ability to produce more red blood cells at high altitudes.

This may result in a decreased oxygen-carrying capacity and a higher risk of developing altitude sickness or other related conditions. However, the exact impact of the CG variant on altitude adaptation is complex and may depend on other genetic and environmental factors as well.

Answer:

Leber’s hereditary optic neuropathy (LHON) is defined as a disorder caused by a mitochondrial mutation that affects the visual and heart cells.

A  defective mitochondria is the primary cause of the LHON because it causes mtDNA is involved in the encoding of ubiquinone oxidoreductase         (subunits of NADH) that is the first complex of the electron transport chain. So, any defect or mutation in mtDNA causes neuronal defects.

Mitochondrial defect due to mutation in amino acid exchanges in ubiquinone oxidoreductase affects optic nerves causing loss of retinal ganglion cells (RGCs) and their axons that leads to vison loss.

Mitochondrial biogenesis is the process in which mitochondrial ATP produced, and ATP transfer to heart and defect in mitochondrial biogenesis causes defect in heart cells.

Answer:

Haploid number of chromosomes.

Explanation:

Before fusion of sex cells i. e. sperm cells and egg cells, there are half number of chromosome present in each sec cell because in the sex cells meiosis occurs. Meiosis is a type of cell division in which a single parent cell divides into four daughter cells having haploid chromosome i. e. half number of chromosomes in each daughter cell. So when these sex cells fuse together, they form a diploid organism.

Explanation:

Answer:

b) capsid

Explanation:

The type of resistance that occurs when bacteria are resistant to beta-lactams as a result of the production of beta-lactamases. The type of resistance this represents is called enzymatic resistance.

Enzymatic resistance against beta-lactam antibiotics is a common mechanism of antibiotic resistance in bacteria. Beta-lactam antibiotics, such as penicillins and cephalosporins, work by inhibiting the activity of bacterial enzymes called penicillin-binding proteins (PBPs), which are involved in the synthesis of the bacterial cell wall. Bacteria can develop resistance to beta-lactam antibiotics by producing enzymes called beta-lactamases, which are able to break down the beta-lactam ring structure of the antibiotic. This prevents the antibiotic from binding to the PBPs and inhibiting cell wall synthesis. Beta-lactamases are classified into different groups based on their structure and function. The most common beta-lactamases produced by bacteria are called extended-spectrum beta-lactamases (ESBLs), which are able to break down a wider range of beta-lactam antibiotics, including cephalosporins. Other mechanisms of resistance against beta-lactam antibiotics include changes in the expression of PBPs or the development of efflux pumps that can remove the antibiotic from the bacterial cell. To combat resistance against beta-lactam antibiotics, several strategies are being developed, including the use of beta-lactamase inhibitors, such as clavulanic acid, which can bind to and inactivate beta-lactamases, and the development of new beta-lactam antibiotics that are less susceptible to degradation by beta-lactamases.
