oxygen is carried by blood to all the cells of body in the form of ___________​

Answers

Answer 1

Answer:

Oxygen is carried by blood to all the cells of the body in the form of haemoglobin.

Explanation:

Oxygen is carried in the blood in two forms:

(1) dissolved in plasma and red blood cells water (about 2% of the total)

(2) reversibly bound to haemoglobin (about 98% of the total).

Haemoglobin is a protein in the red blood cells and carries oxygen around our bodies. At the same time, carbon dioxide that is dissolved in the blood comes out of the capillaries back into the air sacs, ready to be breathed out.

Please find the missing answers to the questions in BOLD.

Explanation:

As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.

The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.

Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).

a. The same gene is mutated in many other individuals with the same kind of cancer.
b. The mutation impacts the function of a known tumor suppressor gene.
c. The mutation is a silent point mutation in a protein-coding sequence.
d. The gene carrying the mutation is known to participate in the cell cycle.

Answers

Answer:

The mutation is a silent point mutation in a protein-coding sequence.

Explanation:

A mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. Mutations can be damaging or beneficial.

There are two types of mutations in cancerous cells:

· Driver mutations, which refer to genetic changes that provide malign cells an adaptative advantage. These mutations drive the cells to tumoral evolution.

· Passenger mutations, also known as neutral mutations, refer to those that do not provide any advantage nor disadvantage to the cancerous cell. These mutations can be between DNI segments where the driver mutations are. Some of these passenger mutations might become driver mutations with time.

Answers

Answer:

- When a neuron is stimulated and sodium channels open, the process of depolarization has begun.  

- Structures of the nervous system surrounding, but not part of the central nervous system are part of the peripheral nervous system

- Two consecutive neurons communicate at a synapse, where they physically come together.  

- Endorphins are a group of natural chemicals that reduce the perception of pain.  

- Supporting cells of the nervous system are collectively called neuroglia

- When potassium channels have been open long enough to go below resting membrane potential, hyperpolarization has occurred.

Explanation:

Neurons undergo depolarization in response to diverse stimuli (e.g., heat, light, electrical, chemical, etc). The depolarization occurs when sodium (Na+) ions pass through specific channels  (i.e., open voltage-gated Na+ channels) into a neuron, which causes an increase in the positivity of membrane potential. On the other hand, hyperpolarization occurs when potassium (K+) channels remain open and Na+ channels reset, thereby producing an increase in negativity of membrane potential. The peripheral nervous system (PNS) is composed of the cranial nerves, spinal nerves, peripheral nerves, and neuromuscular junctions, which connect the Central nervous system (CNS) to the organs, limbs, and skin. Endorphins (e.g., serotonin) are polypeptides secreted by the pituitary gland and CNS to relieve stress and pain. Neuroglia refers to a class of neural cells that have ectodermal (e.g., astroglia, peripheral glial cells) or mesodermal (e.g., microglia) origins. Neuroglia cells are involved in diverse roles, including, among others, the formation of the blood-brain barrier, homeostatic support, provision of nutrients for neurons, structural support to nerve cells, etc.

A 45-year-old woman named Christine is measured as having the following skinfold thicknesses on the right side of her body: Triceps: 14mm; Thigh: 32mm; Suprailium: 28mm. Estimate her body fat percentage.

Answers

Answer:

The skinfold method, the measurement of subcutaneous fat folds, is the most widely adopted field method for the assessment of body fat, especially in children.

It is based on the principle that fat is of a known density and by “summing” measurements of subcutaneous fat thickness across the body, total and regional fat can be estimated.

Skinfold thickness measurements are typically used to rank individuals in terms of relative total “fatness”, or to assess subcutaneous fat at various regions of the body.

Population specific equations are used to derive estimates of percent body fat.

In infancy, it might be the sole tool available for assessing body composition longitudinally as other methods may not be feasible, or may only be suitable for use at body sizes e.g. PEA POD, can only measure infants up to 10kg.

The most generally used field method for determining body fat, particularly in kids, is the skinfold method, which involves measuring subcutaneous fat folds.

What is skinfold method?

Skinfold method is defined as a method for determining how much body fat there is. It entails delicately pinching the skin and underlying fat in several locations using a tool called a caliper. To acquire precise findings using this quick and easy body fat estimation technique, a high level of competence is needed.

It is based on the idea that since subcutaneous fat thickness measurements may be "summed" to estimate total and regional fat because subcutaneous fat has a known density. Measures of skinfold thickness are widely used to categorize individuals based on their relative degrees of overall "fatness" or to assess subcutaneous fat in various bodily regions. Estimates of the percent body fat are derived using equations that are specific to a population.

Thus, the most generally used field method for determining body fat, particularly in kids, is the skinfold method, which involves measuring subcutaneous fat folds.

which fundamental units are involved in force do step Wise ​

Answers

Force = ma

We know, the unit that the S.I. unit of mass is Kg.

We also know that a = (v - u)/t.

We know that v = d/t and u = d/t and the S.I. unit of t(time) is s.

We know that the S.I. unit of d(displacement) is m.

So, the S.I. unit of v is m/s and the S.I. unit of u is m/s and the S.I. unit of t is s.

So, the S.I. unit of a is m/s×s or m/s²

So, the unit of force is

(unit of m) × (unit of a)

= kg × (m/s²)

= kg.m/s²

=

[tex]kg \: m \: {s}^{ - 2} [/tex]

Or more simply,

F = ma

=> F = m{(v-u)/t}

Putting units,

Newton = kg[{(m/s) - (m/s)}/s]

=> Newton = kg{(m/s)/s}

=> Newton = kg(m/s²)

=> Newton = kg.m/s²

=> Newton = kg.m.(s^-2)

8. Two rabbits are bred together. One is heterozygous for agouti coat
(genotype: Cch) and the other is albino. What are the possible phenotypes
of their offspring? Construct a Punnett square to support your answer.

Answers

Answer:

- Parental cross = Cch  x chch  

- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio

Punnett  square:  

          ch         ch

C       Cch       Cch

ch    chch      chch

 

Explanation:

A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular locus. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given locus (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.

Explain how the ear helps humans in balancing.​

Answers

Answer:

The vestibular system which is essential to our sense of balance is located within the inner ear

Explanation:

The vestibular system is the sensory apparatus of the inner ear that provides the brain with the information required for maintaining body balance (postural equilibrium), detecting the position and motion of the head and determining the position of the whole body in relation to gravity. The vestibular system in each inner ear is composed of five organs: 3 semicircular ducts located in the innermost part of each ear (i.e., the inner ear), which are sensitive to angular accelerations (head rotations), and 2 otoliths organs referred to as the utricle and saccule, which are sensitive to linear accelerations. Each semi-circular duct exhibit a different orientation (superior, horizontal, and posterior) in order to sense different movements (e.g. nodding, rotating).
