According to the research, glomerular capillaries and podocytes together form the filtration membrane.

It is the filtration barrier of the renal corpuscle that consists of the endothelium of the glomerular capillaries, the podocytes, and prevents the passage of macromolecules mechanically and electrically.

Podocytes also keep the glomerular filtration barrier stable by removing proteins and immunoglobulins.

Therefore, we can conclude that according to the research, glomerular capillaries and podocytes together form the filtration membrane.

Answer:

Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Together, skeletal muscles and bones are called the musculoskeletal system (also known as the locomotor system). Generally speaking, skeletal muscle is grouped into opposing pairs such as the biceps and triceps on the front and back of the upper arm. Skeletal muscles are under our conscious control, which is why they are also known as voluntary muscles. Another term is striated muscles, since the tissue looks striped when viewed under a microscope.

Cardiac muscle – the muscle specific to the heart. The heart contracts and relaxes without our conscious awareness.

The feature enables the paramecium to move is moves through cilia.

Protozoan that moves by cilia, free-living, unicellular, bearer of a translucent and flattened body. They reproduce by simple division and are visible under the light microscope.

Paramecium, as a ciliated protozoan, has peculiar characteristics to be defined. they are also used to bring food into the cytostome where it will be phagocytosed after passing through the cytopharynx.

Microscopic folds that extend from the apical surface of certain epithelia to increase the surface area for absorption and secretion are called Microvilli.

Microvilli are cellular membrane protrusions that improve diffusion surface area while minimizing volume increase than can be seen through a microscope. Plasma membrane covers microvilli, enclosing cytoplasm and microfilaments (the main structure is given by the actin filaments).

In the gastrointestinal system, microvilli serve as the major surface for nutrition absorption. The microvillar membrane is filled with enzymes that help in the breakdown of complicated nutrients into simpler molecules that are more easily absorbed because of its critical role.

Exitatory neurotrasmitter excite the postsynaptic memebrane by increasing the action potential effects. They allow the messages passage from one cell to the other.

Neurotransmitters might be either excitatory or inhibitory.

As the term suggests, excitatory neurotransmitters are in charge of exciting the postsynaptic cell.

Once the neurotransmitter is released from the presynaptic membrane, it travels through the synaptic space until it reaches the postsynaptic membrane.

When the molecule meets its receptor, it triggers a series of events that excite the receiving neuron increasing the action potential effects and allowing messages to be passed from one cell to the other.

Answer:

A larger population density will help reduce the average costs of the transport network. Areas of high population density have not seen the food shortages because of improved yields from agriculture and the ability to trade food. Economic growth will be comparatively more than low density area.

Answer:

The modern organisms would have more muscular bodies

Explanation:

Taking into account the definition of density and Avogadro's Number, you take 2.0286×10²⁵ molecules of air.

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

In this case, you know that:

Replacing in the definition of density:

[tex]0.97 \frac{g}{mL}=\frac{mass}{1000 mL}[/tex]

Solving:

mass= 0.97 [tex]\frac{g}{mL}[/tex]  ×1000 mL

mass= 970 g

Air has an average molar mass of 28.8 g per 1 mol. Then 970 grams are contained in 33.68 moles.

Now, considering the definition of Avogadro's number you can apply the following rule of three: If 1 mole of air contains 6.023×10²³ molecules, 33.68 moles contains how many molecules?

amount of molecules = (33.68 moles× 6.023×10²³ molecules)÷ 1 mole

amount of molecules= 2.0286×10²⁵ molecules

Finally, you take 2.0286×10²⁵ molecules of air.

The Pacific Ocean, A body of seawater that stretches from the Antarctic region in the south towards the Arctic Circle in the north and is sandwiched between Asia and Australia on the west and South and North America on the east. It covers roughly one-third of the earth's surface and is arguably the largest of the world's oceans. Its total area, excluding neighbouring seas, is estimated 63,800,000 square miles (165,250,000 square kilometres), which is twice the size of the Atlantic Ocean and larger than the entire land area of the world.

Question: What day is considered to be the first day of a female's reproductive cycle?

Answer: When hormone levels are low and the uterus lining is shed.

The first day of a female's reproductive cycle is when hormone levels are low and the ovary releases an egg. This is known as ovulation and is the most important part of a woman's menstrual cycle.

During ovulation, the egg's follicle bursts open and is released, travelling down the fallopian tube towards the uterus.

If the egg is fertilised, it will implant in the uterus and a pregnancy will begin; if it is not, it will be reabsorbed by the body, and the cycle will restart.

The vertebrates that first invaded the land possessed a series of pre-adaptations, such as air-breathing and limb-based locomotion, that allowed them to move about effectively on land; however, other behaviors such as reproduction and swallowing likely tied these vertebrates to the water

When moving to land, animals faced several changes to adapt to the new environment, like lung and limbs development, tegumentary cover, and internal fertilization.  

Any change to a new environment needs adaptations.

Aquatic animals had to face many changes in their morphology and physiology when changing to terrestrial habits. Some of them are,

The most significant change is probably lung development, needed to produce gas interchange between tissues and the air.

Once on the ground, animals need to interchange oxygen and carbon dioxide with air. They managed to do so through the respiration process in which the circulatory and respiratory systems work together.

Animals needed to develop a new thicker and harder tegumentary cover.

It needed to be more resistant, especially to avoid or reduce dehydration.

Also, the tegument provides protection when facing new environmental pressures -predation among them-.

Another significant change was limb development, which was obviously needed to move on the ground.

Locomotion on the ground required a new pattern of bone arrangement and many muscle changes.

The muscular system suffered many modifications because animals needed to move facing gravity pressure.

Animals needed to face another change related to their reproductive system.

They could no longer make use of external fertilization, as they used to do in aquatic environments.

They developed reproductive organs needed to insert sperm cells into the female body and fertilize the egg cells inside the females.

The food chain represents the linear sequence of organisms through which nutrients and energy gets transferred from one trophic level of the organism to another.

In a food chain, the trophic level may be characterized as the hierarchical series that is illustrated by organisms that are the exact number of steps extracted from the primary producers.

The order of the food chain is:

Grass plants → Grasshopper → Shrew → Owl.

The grass plant is a producer in this food chain, a grasshopper is a herbivore (primary consumer), the shrew is a carnivore (secondary consumer), and an owl is an omnivore (tertiary consumer).
