What type of asexual reproduction is snail?

Answers

Answer 1

However, some hermaphrodite snails reproduce asexually. In other words, the snail fertilises its own egg with its own sperm.

Some hermaphrodite snails can reproduce on their own without the help of another snail (this is called asexual reproduction). Even though some snails are hermaphrodites, they still require a partner to procreate (this is called sexual reproduction). Nerite snails do not reproduce asexually, unlike the majority of aquatic snails. Similar to fish, a female nerite snail will lay eggs that the male will fertilise. The developing larvae will then be dispersed throughout the tank with the eggs.

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!!

identify the type of blood vessels that artherosclerosis will affect. Why is it important that these blood vessels be elastic and flexible?

Answers

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.

The human hands and feet have similar types and numbers of bones. However, hands and feet are very different in their appearance. What physical differences do you notice between the hands and feet? How might these differences relate to differences in the function of these body parts? Would you expect other primates to have hands and feet differently like this? Why or why not?

Answers

Answer:

Hands have a larger range of dexterity compared to feet. Longer tendins and stronger grip strength, they are made for more intrucite tasks such as making and using tools. Feet have a larger surface area, made for holding large amount of weight, shorter bones and tendins allow for easy acceleration and no extra flesh to get in the way. Other more primitive species will not have the  feet we have due to evolution. They simply do not have the evolved sense of brain pwer hians haev in order to make tools. So they have more need for speed, grip exc. in feet to escape pradators and live day to day. Where on the other hand humans do not.

Explanation:

The metatarsals that can be found in the foot are larger than the metacarpal bones that ​are in the hands.

It should also be noted that the phalanges of the hand are larger than that of the foot. The way that the metacarpal of the thumb is built is vital for mobility and movement.

Primates have hands and feet that are different from that of humans because they use their hands and feet for grasping. They also have strong clavicles and flexible shoulder joints. This enables them to climb and grasp things firmly.

What can the scientists most likely expect to find in the layers of rock that are about the same age as the impact?

Answers

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.

Metabolic acidosis can occur as a side effect of taking acetazolamide because: Select one: a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. b. chloride ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. c. bicarbonate ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions. d. chloride ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions.

Answers

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.

Why does a larger quantity of water take longer to freeze ?

Answers

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.

Has the change in the environment (in this case the food preference of predators) caused natural selection to start occurring in this fish population?

Answers

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 vascular tissue of a plant transports various substances. Which substance would you expect to find in phloem, but not in xylem? a. Glucose b. Iron c. Potassium d. Water

Answers

I think the ans is d.water

While xylem transports water and mineral salts up from the roots to various parts of the plant, phloem transports sucrose and amino acids between the leaves and different parts of the plant. Thus, option D is correct.

What is the function of xylem and phloem?

Water and dissolved minerals are distributed upward through the plant by the xylem, from the roots to the leaves. The phloem carries nutrients from the leaves to the roots.

The vascular cambium gives rise to xylem, vascular tissue that moves nutrients and water throughout the plant.

The vascular tissue known as phloem, which carries big molecules like sugar, develops outward from the vascular cambium. Increased xylem and phloem cells are produced when the vascular cambium cells divide.

Therefore, water is the substance that you expect to find in phloem.

When soil first forms over bare rock, what is it made of?

Answers

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.

What is Soil?

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.
