Answer:

a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized.

Explanation:

Metabolic acidosis is an electrolyte disorder characterized by a pH of less than 7.40 and low bicarbonate (HCO3) levels in the blood. This disease may be due to 1-an increasing acid production, 2-loss of HCO3 (which acts as an acid buffer agent), and 3- by a decreasing ability of the kidneys to maintain normal acid levels. The kidneys contribute to maintaining the acid–base balance by excreting hydrogen ions (H+) into the urine and absorbing HCO3 from the urine. In metabolic acidosis, kidneys are unable to remove enough acid and conserve sodium ions (Na+), which is normally done by excreting ammonia in the urine.

Answer:

Yes.

Explanation:

Yes, change in the environment conditions leads to the initiation of natural selection in this fish population if the food preference of the predators changes because changes in the food preference of predator causes lowering of population which can't be eaten by the predator earlier. Changing rainfall and drought patterns reshaping the population and existence of fish by availability of type of food to predators which ultimately leads to natural selection among population of fish.

The correct answer to this open question is the following.

Although you forgot to include the context of the question and the options to answer it, we can comment based on our knowledge of this topic.

What scientists most likely can expect to find in the layers of rock that are about the same age as the impact is evidence of a gradual change of one species over time.

This question has to have the following context. Scientists found evidence of a large meteor impact on the coast of the Yucatán Peninsula in Mexico.

Scientists, researchers, and geologists use special methods to date rocks and fossils on planet Earth. In this case, they have used a method called radiometric dating. These methods are based on radiation. Yes, they use the natural radioactive decay of potassium, carbon, and other elements to get to the most exact date on when things happened. In this case, the time of the meteor impact on the Yucatán Peninsula in southern México.

Answer:

A library will not receive federal funds.

Explanation:

Answer:

If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases.

Explanation:

Answer:

As the quantity of liquid is bigger it will take longer to freeze because more energy will have to be used. There is a state of matter that water has which is called super cooling this is where the water is at a freezing tempture but ice crystals haven't be formed correctly. Different liquids freeze at different temperatures. Water will freeze faster than liquids with salt or sugar in them. Some liquids freeze faster than others because of viscosity, or thickness of the liquid. Thicker liquids will freeze more slowly and some will not freeze at all.

C. captive breeding programs

Explanation:

Captive breeding programs aim to breed more of an animal that may have been struggling to survive, they may even be beneficial to biodiversity.

Explanation:

Secondary succession occurs as result of a disturbance that greatly alters an ecological community. Fires, storms, floods and removal of timber by humans can cause either the complete or partial destruction of vegetation. The availability of resources affects species diversity for each trophic level undergoing secondary succession.

Answer:

Atherosclerosis affects arteries, these blood vessels are elastic and flexible in order to allow good blood circulation

Explanation:

The blood vessels are classified into three types: arteries, veins, and capillaries. An artery is a muscular blood vessel that is able to carry blood away from the heart to different parts of the body. Healthy arteries need to be elastic and flexible in order to adjust their diameter and thus control blood flow by maintaining blood pressure. Arteriosclerosis is a chronic disease caused by the accumulation of fatty substances (especially cholesterol) in the artery walls, thereby difficulting blood circulation by thickening and hardening these walls.

Answer:

D. Sami had low birth weight as a lamb but quickly grew into a large sheep.

Explanation:

The Sami lamb is an example of culled because it has the characteristics of quick growth. Culling is the process of separating organisms from a group of same type of organisms due to presence of desired or undesired characteristics. Sami sheep has a unique characteristic of having less weight at time of birth but having quick growth features that make to gain more weight and become large sheep so this sheep is removed from the population for its good traits.

Explanation:

Answer:

Let ‘Xᶜ’ be the recessive allele for colour blindness and ‘X’ be the normal (dominant) allele.

Since Abby's father was colour blind, Abby must be a carrier for the same.

Which means Abby's genotype would be ‘XXᶜ’.

Now, Ryan is not colourblind which means his genotype would be ‘XY’.

Now, talking about their daughter, she would inherit a normal ‘X’ from Ryan and either ‘X’ or ‘Xᶜ’ from Abby.

Which means she wouldn't be colourblind but she might be a carrier of the disorder.

XXᶜ × XY

⬇️ ⬇️

X, Xᶜ X

↘️ ↙️

XX , XXᶜ

Their daughter will have either XX genotype or XXᶜ genotype.

And her chances of being colourblind thus, becomes zero.

Answer:

Most foods especially carbohydrate diets ends up in the blood stream in the form of sugar causing a spike

Explanation:

The high sugar level in the blood then penetrate the body cells in an uncontrolled manner since there is no enough or no insulin produced to regulate it.

Answer:

A is the correct answer.

Answer:

Explanation:

Weathering and erosion produce ever smaller rock particles which,

when mixed with dust and decayed organic matter over time ,

result in different types of soil .

Soil is formed by the process of weathering. The soil is the uppermost layer of the surface of Earth. The first formed soil contains pieces of rocks and other particles.

Soil is the uppermost thin layer of material covering the earth's surface. It is formed from the weathering of large rocks. It is made up of mineral particles, organic materials, air, water and living organisms like bacteria.

The lichens are the pioneer species which invade the bare rocks and convert them into soil. They secrete acids which dissolve the rocks. This helps in their weathering and formation of soil. Mosses grow on the rocks along with the lichens to form a mat over the substratum.

Under the action of factors like heat, cold, rain, wind, and other atmospheric factors, the rock breaks down physically into the parent material of the soil.

Answer:

hi

Explanation:

The lens is a material made of glass or plastic bounded by two surfaces. ... A mirror is a reflector that is shiny from one side and reflects the light rays coming from the object to make it appear as an image to the other side. The lens is of two types viz: Concave lens and convex lens.

have a nice day

Answer:

The difference between mirror and lens lies in how light reflects when falls over their surface. When light interacts with any surface, mainly two things happen; Reflection and Refraction. The main difference between mirror and lens is that image forms by reflection, as the light falls on a mirror. In lens, the image is formed by refraction.

What are the collecting chambers of the heart? What are the pumping chambers of the heart? The heart is made up of four chambers. The upper chambers are the called atria and act as the receiving chambers. There are four valves within the heart, which help control the direction of blood flow. Blood low in oxygen returns from the body and enters the right atrium.  The lower chambers are called ventricles; these are the pumping chambers.           I really hope this helps!! Have an amazing day <3
