Bone, ligaments, tendons, cartilage and fat tissue is common to all types of connective tissue.

Bone is a connective tissue which is metabolically active and the main function of bone is to provide mechanical or structural support as well as perform movement, and protect important organs of the body.

The bone is made up of bone cells known as osteocytes and extracellular matrix. The total number of bone human body contain is 206 bones including bones of spine, legs, arms, ribs, and skull.

Bones are made up of calcium and carbonate and they have bone marrow in which blood cells are produced. By nature bones came in category of living and they are active tissue .

There are several types of bones such as flat bones, short bones, sesamoid bones, and long bones. The function of bone is to protect vital organs of the body.

Answer:

DNA is indeed a genetic material but not the "only genetic material" as in retroviruses it is the RNA which carry the genetic information and whatever there inside a cell in all organisms as well as even in the environment of the cell in multicellular organisms, are as important as DNA. There are cells which survive and are functionally viable for several days without having any genetic material like mature erythrocytes.

Answer:

weathering

Explanation:

weathering is the breaking down of the rock,

erosion is the movement of sediment from broken rocks

deposition is the dropping of a sediment in a new place

Answer:42%

Explanation:

The percentage of the population is heterozygous for this gene is 42%. The correct option is C.

According to the Hardy-Weinberg equilibrium, if no unfavourable influences exist, genetic variation in a population will remain stable from one generation to the next.

Calculating the genetic diversity of a population at equilibrium can be done using the Hardy-Weinberg equation. A fundamental idea in population genetics that G. H. Hardy and Wilhelm Weinberg separately described in 1908 is now known as the Hardy-Weinberg equation.

The importance of the Hardy-Weinberg law is that it provides a way to assess how accurately a population's genetic makeup has changed over time. We could only determine if the population was in Hardy-Weinberg equilibrium with the genetic makeup.

We know that,

\(p^2+2pq+q^2=1\)

Here,

p = 0.70

q = 0.30

So,

\((0.70)^2+2pq+(0.30)^2=1\)

2pq = 42%

Thus, the correct option is C.

Answer:

2Hz

Explanation:

What is the frequency of a wave if its period is 0.5 s?

2 Hz

As the frequency of a wave increases, the time period of the wave decreases and as the frequency of a wave decreases, the time period of the wave increases. So, the answer is, f = 1/0.5 = 2 Hz.

The food eaten in the zones in the lake include;

Littoral Zone - Sea weed

Limnetic Zone - Plants

Euphotic Zone - Shrimps

Benthic Zone - Calms of shrimps

Littoral Zone: This zone is the lake or pond's shoreline. It is made up of the area between dry land and open water that can be very narrow or very wide.

Limnetic Zone: The open water area of a lake or pond is generally classified as the Limnetic Zone. In oligotrophic ponds and lakes, this is a much larger section of water than in eutrophic bodies of water.

Euphotic Zone: The upper portion of the Limnetic Zone near the water's surface is known as the Euphotic Zone or Epilimnion (warm water region). This is the part of the water that gets sunlight. The zone ends when sunlight cannot penetrate the water.

Benthic Zone: The Benthic Zone consists of organic sediments and soil at the bottom of a pond or lake. This zone will expand as the body of water ages. It is regarded as the digestive system of a pond or lake.

Following the Hardy-Weinberg equilibrium theory, in a population of six million people, 1,080,000 individuals are healthy and carriers (heterozygous) for the trait.

The Hardy-Weinberg equilibrium is a theory that states that populations in equilibrium get the same allelic and genotypic frequencies generation after generation.

These populations do not evolve. No evolutive forces are acting on them.

Assuming a diallelic gene, frequencies are

Allelic frequencies

Genotypic frequencies

In a population in equilibrium,

We will consider these equations to solve the problem.

Because we have the frequency of the homozygous recessive genotype, we can get the allelic frequency.

Now, by clearing the equation p + q = 1, we can get the dominant allele frequency. And then, the frequency of the homozygous dominant genotype.

Finally, we can get the frequency of the heterozygous genotype

The number of individuals with each phenotype in the population is,

The image represents the continental-continental boundary. When two continental plates collide, that's another kind of convergent plate boundary. The continental lithosphere is very thick and has a low density. The continental lithosphere cannot subduct. So when two mainland plates impact, they simply crush together.

Plate tectonic boundaries come in three varieties: plate boundaries that are transformed, divergent, and convergent. The three primary types of plate boundaries are depicted in this image: transform, convergent and divergent.

Aquaculture as a form of farming is always characterised by the farmer's efforts to increase the rate and calibre of aquaculture species' growth.

Contrasted with commercial fishing, which includes capturing wild fish, aquaculture involves raising populations of freshwater, brackish water, and saltwater species in Aquaculture or semi-natural environments.

Systems of culture and rearing in which human intervention is focused on stock reproduction in addition to capture are referred to as extensive aquaculture. These approaches, as opposed to fishing, allow for the selective expansion of production of the species that are most in demand by humans.

There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.

The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.

The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.

The  physiological changes that occur with aging cause stress incontinence. Therefore, the correct option is A, C, E and F.

Aging refers to progressive physiological changes that occur in the body of an organism that leads to senescence.Estrogen deficiency can lead to changes in the tissues of the urinary tract, including the urethra, which can result in decreased support and weakening of the urinary sphincter.

Decreased bladder capacity can result in more frequent and urgent voiding, which can increase the likelihood of incontinence. Unstable bladder contractions can also contribute to incontinence. Finally, weakening of the urinary sphincter, which is responsible for controlling the flow of urine, can lead to stress incontinence.Therefore, the correct option is A, C, E and F.
