XX=Female XY=Male.
your best friend has five children and they are all boys. They are expecting their 6th child. What would be the probability for their 6th child to be a girl? Why

Answers

Answer 1

Answer:

50% or 1/2

Explanation:

The probability of their 6th child being a girl would be 50% or 1/2.

During meiosis, the female produces X eggs while the male produces X and Y sperms. A random fusion of gametes then occurs during fertilization.

                             XX    x    XY

       XX (female)   XY (male)   XX (female)   XY (male)

XX - 1/2 or 50%

XY - 1/2 or 50%

Hence, the probability of producing a girl is 1/2 or 50% irrespective of the number of kids a couple might have produced already.

Commensalism refers to a relationship in which one organism benefits, whilst the other organism is not affected. For this to be a commensal relationship, either the algae or the sloth must benefit, but not both, otherwise that would be mutualism.

How does heart rate affect blood pressure

Answers

Answer:

Does heart rate affect blood pressure?

A rising heart rate does not cause your blood pressure to increase at the same rate. Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily. When you exercise, your heart speeds up so more blood can reach your muscles.

Explanation:

Answer: As your heart beats faster, healthy blood vessels will expand in size to allow increased blood flow, which helps your blood pressure remain relatively stable.

How does competition limit the dispersal of organisms? *

Answers

Answer:

Three factors that limit dispersal of a species are physical barriers, competition, and climate. Physical Barriers include water, mountains, deserts, and canyons because these barriers are hard for most organisms to cross, they limit the movement of organisms.

If an animal has to pass through another animals territory to disperse, that animal may be killed or injured in the process, so it may opt not to move or not to move as far as it should.

(Q002) Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living non primate animal that is also a biped. Then, compare its bipedalism with our bipedalism. Try to consider how it moves and some of its possible adaptations (such as limb length). Use resources in your classroom, credible online sources, or books to help you if necessary.

Answers

Answer:

One good example of a living non-primate that is also a biped is a Kangaroo.  With so much power in their legs and vertebral column like humans, kangaroos are biped, but they leap rather than walk.  Their legs are usually bigger than their arms, which enables them to push their whole body off the ground.

However, kangaroos are not just bipedal or quadrupedal but they are both.  They also hop bipedally like rodents and many birds, with some displaying skipping gaiety.  In addition, chimpanzees, gorillas, gibbons, macaques, capuchins, birds, many lizards, and (at their highest speeds) cockroaches run bipedally.

Explanation:

Bipedalism is the use of two feet for standing and walking.  Nearly all primates are capable of bipedalism, although most of the primates spend their time on all fours.  Primates are known to move bipedally, but they also use bipedalism to stand up on their hind legs to reach food, look for predators, and for social display and communication.

Are all electrolytes the same in their indications? Explain

Answers

Answer: Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help Balance the amount of water in your body.Balance your body's acid/base (pH) level .Move nutrients into your cells, Move wastes out of your cells, Make sure that your nerves, muscles, the heart, and the brain work the way they should. Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink. The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance. Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.

The two structural classifications are projection neurons and local inter-neurons.
Function classifications are made up of two subcategories: excitatory and inhibitory.
Histological classification includes bipolar, unipolar, and multipolar.
Classifications using a combination of structural, functional, and neurotransmitter type provide the most robust and useful description.
Classification by neurotransmitter type alone provides the most useful description.
A. I only
B. III only
C. I, II, and V only
D. I, II, III, IV, and V
E. I, III, and IV

Answers

Answer:

The correct answer is option D. I, II, III, IV, and V

Explanation:

Neurons are the nerve cells that transmit the information in the form of nerve impulses throughout the body. Neurons are an important part of the body and nervous system as neurons control the movement, any other functions of the body. Classification of neurons is presented on different ways such as structural basis, on the basis of functions, histologically, or on the basis of neurotransmitters used by neurons.

Histological classification - bipolar, unipolar, and multipolar.

Function classifications - excitatory and inhibitory.

structural classification - projection neurons and local interneurons.

All type of classification together makes a robust and very useful description of the neurons.
