The cells that make up skeletal muscular tissue are somewhat unique for having:

O cell walls instead of cell membranes.
O especially porous cell membranes.
O no mitochondria.
O cells with multiple nuclei.

Answers

The cells that make up skeletal muscular tissue are somewhat unique for having cell walls instead of cell membranes and is denoted as option A.

What is Cell wall?

This is mostly found in the outer region of the cell membrane and is a rigid, semi-permeable protective layer which consists of lipids, cellulose and polysaccharides needed for its functions.

The cell wall is mostly found in plants but at the same time they are present in some cells of the body such as that of the skeletal muscular tissue due to the rigorous activities being performed by them.

This helps to maintain the structural integrity of the cells and ensures that movement is easily done which is the reason why they are present instead of cell membranes hence option A is correct.

i dont know if it is group 2 or group 14

Answers

The group 2 Elements The Alkaline Earth Metals and the group 14 carbon.

Once you have the atomic number of an element you can find its period number and group number. The periodic number refers to the number of shells an electron in an element occupies, while the periodic number refers to its valence electrons. Group 14 is the carbon family. The five members are carbon silicon germanium tin and lead.

All of these elements have four electrons at their limited energy levels. Of the group 14 elements, only carbon, and silicon form bonds as electron-sharing non-metals. The carbon family is also called carbon group 14 or group IV. This family was called petrel or tetragon because the elements belonged to group IV or as a reference to the four valence electrons of the atoms of these elements. This family is also called crystallins.

White blood cells, called leukocytes, are very different in structure and function than red blood cells. White blood cells help fight infections, parasites, and bacteria. They do this by engulfing pathogens and synthesizing antibodies which are made from proteins. In addition white blood, cells can reproduce unlike red blood cells.

Answers

Many white blood cells can't divide and they have the ability to reproduce on their own.

How do white blood cells reproduce?

White blood cells are not similar to other types of cells that are present in our body. They act like single-cell organisms which can move on their own and can feed on other cells and bacteria. Many types of white blood cells can't reproduce on their own so they are produced in the bone marrow. In a person that has normal bone marrow, the number of white blood cells can double within hours. It is a type of blood cell that is produced in the bone marrow and found in the blood lymph tissue. White blood cells are part of the immune system of our body. White Blood Cell protects Red Blood Cell, as it tries to protect the red blood cells from pathogens.

So we can conclude that the cells which can move freely and feed on pathogens and bacteria that can harm our body are known as white blood cells.

The Loch Raven Reservoir supports a variety of organisms at all times of the year. There is an algal bloom this year. How would the environment be expected to change?​

Answers

It is expected that the algal bloom in the Loch Raven Reservoir would change by decreasing the amount of available biomass.

What is the direct consequence of an algal bloom?

The direct consequence of an algal bloom is an increase in the amount of available oxygen in the aquatic system and a drastic reduction in the light that enters into this ecosystem, which reduces the amount of biomass because plants are unable to produce photosynthesis.

Therefore, we can conclude that the consequence of an algal bloom is a decrease in the biomass that supports the trophic chain in this aquatic ecosystem.

what is sexual reproduction system ​

Answers

The process of creating new creatures through the union of the genetic material from two individuals of different sexes is known as sexual reproduction.

The majority of creatures have chromosomes, which contain the genetic material, in the nuclei of their reproductive cells, known as gametes, which mate to produce a diploid zygote. The fusion of a haploid female gamete (egg cell) with a haploid male gamete is the process of sexual reproduction.

These gametes combine during fertilization, creating a diploid zygote as a consequence. A unique organism that is genetically separate from its parent species emerges from the zygote. Contrast this with asexual reproduction, in which an organism reproduces without the use of gametes and the progeny are identical clones of the parent.

However, sexual reproduction outperforms asexual reproduction in terms of boosting genetic diversity and enlarging the gene pool. Additionally, it guarantees that a species' chromosomal count will not change over successive generations. The two main methods of sexual reproduction are conjugation and syngamy.

The production of silver grew over the centuries, but when Europeans first went to America, silver began to be used in many new and different ways. By the 19th century, nearly 120 million troy ounces were being produced annually. Now, more than 5000 years after ancient cultures first began to mine this precious metal, an average of 671 million troy ounces is mined every year. In earlier times, silver was thought to have magical properties and it was considered to be useful in keeping bad spirits away. Nowadays, most people think of silver in relation to ornaments. But it is significant for its antibacterial properties too. The ancient Phoenicians kept water, wine and vinegar in silver vessels to ensure freshness. It is only recently, however, that scientists have discovered how silver works. Quite simply, silver destroys the ability of bacteria to form the chemical bonds which are essential to their survival. When bacteria and silver come into contact, the bacterial cells fall apart. Today, there are bandages and ointments that use silver as an active ingredient. Silver promotes the growth of new cells, which in turn increases the rate of healing. This makes silver especially valuable for treating burns and wounds. Another key use for silver is in the millions of water purifiers that are sold each year. Silver prevents bacteria from building up in filters so that they can work effectively. Research has shown that silver, together with oxygen, cleans water. This means that other chemicals, such as chlorine, do not have to be used. Silver is therefore starting to be added to water purification systems in hospitals, community water systems and swimming pools. Scientists hope that silver will be able to be used in helping to produce clean drinking water in countries where water-borne illness is a problem. Current research shows that this use of silver is an exciting development for the global water supply. In the past, silver was often used to decorate places of worship, and many people saw it when they went to pray. Today, there is probably much more silver around us, but we do not necessarily see it. For example, every time you travel in a motor vehicle you are surrounded by pieces of silver. Every electrical action in a modern car is activated with silver-coated contacts. Basic functions such as starting the engine and opening power windows .all need a special switch that has a silver covering. Another important feature for our driving safety is the silver-ceramic lines fitted into the rear window.
