how does excretion occur in human beings​

Answers

Answer 1

Answer:

Humans have two kidneys and each kidney is supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney.

Answer:

Allele G represents the strong jaw, and allele g represents the weak jaw. This is because as the generations go by, allele G’s population increases, but allele g’s population decreases. If hard shelled animals are the only foods available to them, you would need a strong jaw to eat them. This means that allele g wouldn’t be able to eat these reptiles, so their population would decrease from lack of food.

Why do earthquakes occur near the San Andreas fault?
A
One plate slowly pushes the other plate up.
B) A trench is created as one plate slides under the other plate.
Portions of the plates get stuck and then suddenly loosen and move.
D
One plate pushes hard enough to reverse the motion of the other plate.

Answers

Answer:

C.

Explanation:

Basically a faster explanation is the san andreas fault is a transform boundary. If you have an oreo break one of the top pieces and slide them slowly it will get stuck causing an earthquake.

Earthquakes occur near the San Andreas fault because portions of the plates get stuck and then suddenly loosen and move. Hence option C is correct.

What is earthquake?

Earthquake is defined as the abrupt release of energy in the Earth's lithosphere that causes seismic waves and causes shaking of the planet's surface. Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault. The seismic waves that cause the ground to tremble are brought on by this quick release of energy.

According to new University of Southern California research that contributes to the understanding of how earthquakes occur, tremors along a notorious section of California's San Andreas Fault seem to be fueled by thermal instability brought on by frictional shear occurring much deeper in the Earth than previously thought.

Thus, earthquakes occur near the San Andreas fault because portions of the plates get stuck and then suddenly loosen and move. Hence option C is correct.

Is a meander predominantly formed by erosion or deposition?

Answers

Answer:

Overtime organisms change sometimes they change so much of the sentence may be completely different for their ancestors what must happen for this process to occur

Answers

Answer:

In order to survive in the changing environmental conditions.

Explanation:

Changes occur in the body of an organism which make them different from their ancestors because these organisms evolve with the passage of time due to difference in environmental conditions. If these organisms can't evolve, they can't tolerate that environment and climatic condition and also become extinct so this process occur in the organisms in order to survive that different environmental conditions so we can say that this change is necessary in the organisms to survive.

a. density-dependent factors
b. all limiting factors
c. density-independent factors
d. environmental factors

4. which of the following is a density-dependent factor?

a. hurricane
b. water availability
c. warm weather
d. forest fire

Answers

Answer: 1. a. logistics model of growth

2. a. environmental conditions

3. b. all limiting factors

4. b. water availability

Explanation:

1. a. logistic model of growth will show the increase in population of a species in accordance with the carrying capacity exponentially but when the population will experience the scarcity of resources it will decline considerably.

Carrying capacity is the total number of members of the population of a species that an ecosystem can sustain by providing resources.

2. b. All environmental conditions which favor the survival of the living beings will contribute to the carrying capacity for example food, water, shelter, and other resources.

3. b. Limiting factor is the one which limit the chances of survival and growth of a particular species in an ecosystem. For example, scarcity of food, here food is the limiting factor.

4. d.  A density dependent limiting factor is the one which affects the population of the species based upon the density. The water availability is a density dependent limiting factor because the more the density or abundance of a population more will be the scarcity of water as it will be required by all organisms. So, the species population may experience decline due scarcity of water.

Explain how the respiratory system and circulatory system cooperate to provide the body’s cells with a constant supply of oxygen.

Answers

Answer:

In the respiratory system, you inhale oxygen which is transferred to the blood in the alveoli and circulated throughout the body. The blood in the circulatory system has a protein called hemoglobin which binds to the oxygen and carries it throughout the body. This oxygen is then given to the different cells for cellular respiration. It then carries the waste products (CO2) of cellular respiration back to the lungs and it is exhaled out.

Light travels through the eye by entering through the protective layer called the cornea (17). It then moves through the opening of the pupil which is surrounded by the iris (18), which is a muscle. It will then go through the transparent structure behind the pupil known as the ______________(19) that changes shape to help focus images on the retina in a process known as ________________ (20) The retina contains the photoreceptors known as the _________________(21) and ________________(22). It is there that the actual process of transduction occurs when the photoreceptors excite the ________________(23) cells which in turn send the message on to the _______________(24) cells whose axons make up the optic nerve. The information will then travel to the ____________________(25), which is the sensory switchboard within the brain and end up in the ____________________ (26) lobes where the information is processed specifically within the primary ____________________cortex (27).

Answers

Answer:

The correct answer is - 17) Cornea  , 18) Iris  , 19) Lens, 20) Accommodation , 21) Rods, 22) Cones,  23) Bipolar, 24) Ganglion , 25) Optic Nerve, 26) Occipital, 27) Visual.

Explanation:

The protective layer called the cornea that allows light to enter travel through it to the eyes. Light moves through the pupil surrounded by the muscle called the iris and travels through the lens, a transparent structure that changes its shape on the basis of the intensity of light to help focus images on the retina during the accomadation process. Photoreceptors that are present in the retina are called cones and rods.

The process of transduction takes place when these photoreceptors excite bipolar cells to send signals or messages to the ganglion cells that have axons that make the optic nerves, the sensory switchboard within the brain, and get the messages sent by the photoreceptors. These optic nerves end in occipital lobes where all the signals and messages are processed specifically within the region called the primary visual cortex.

why are manure better than fertilizers​

Answers

Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.

Answers

Answer:

D. A deer has flat teeth for chewing plants.

Explanation:

Adaptation, which is the ability of an organism to survive changes in its natural environment, can either be structural, behavioral and physiological. Structural adaptation is the possession of a physical or structural feature by an organism to enable it survive or adjust to change.

According to this question, the FLAT TEETH possessed by the deer for chewing plants is an example of structural adaptation because the deer posseses a structural feature (flat teeth) that allows it to feed on plants for survival.
