What percentage of those over age 65 can see well without eyeglasses? 1.33 percent 2.10 percent 3.17 percent 4.26 percent.

Answer:

From solutions that evaporate

Explanation:

Minerals can form in different ways. According to the question, minerals crystallize from a material dissolved in water when the solution evaporates. When a material dissolves in water, it forms a solution i.e. water + dissolved material.

The element constituents of the solution can aggregate to form a solid mineral, which will be left to crystallize when the solution undergoes evaporation i.e. liquid changes to gas. A very good example is when salt dissolves in water to form a salt water solution. When the water of this solution evaporates, salt crystals are left, which can crystallize to form minerals.

Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.

Explanation:

Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.

Explanation:

IF IT IS CORRECT PLEASE MARK AS BRAINLIEST

The option that includes an example of each type of symmetry and asymmetry is jellyfish, sea anemones, and sponges. Thus, the correct option for this question is A.

In biological science, symmetry may be defined as the repetition of the parts in an animal or plant in an orderly fashion. It refers to a correspondence of body parts, in size, shape, and relative position, on opposite sides of a dividing line or distributed around a central point or axis.

There are four types of symmetry that occur among animals: spherical, radial, biradial, and bilateral. While Asymmetry means the absence of symmetry as the body of the organism cannot be divided into parts along any one plane. Jellyfish and sea anemones possess radial symmetry.

Therefore, jellyfish, sea anemones, and sponges represent an option that includes an example of each type of symmetry and asymmetry.

the three kinds of nitrogenous wastes based on the energy required to synthesize them are arranged; Ammonia < urea < uric acid.

Nitrogenous wastes are the nitrogen compounds that organisms use to get rid of excess nitrogen. Ammonia, urea, and uric acid are the most common nitrogenous wastes that animals excrete. Protein metabolism generates all of these nitrogenous wastes.

Ammonia is the most toxic of these nitrogenous wastes, and it is the most common but requires the least energy. Urea is more harmful than uric acid, but it is less harmful than ammonia, reducing the amount of energy required to synthesize it. Uric acid is the least harmful, a non-poisonous particle with four nitrogen molecules. This is useful for birds and reptiles that lay hard eggs because it eliminates the most nitrogen, uses the least amount of water, and is not toxic. It also takes the most energy input.

Answer:

a. Each strand of the double helix serves as a template for a new strand.

Each strand of the double helix serves as a template for a new strand. The correct option is A.

The operation by which the genome's DNA is copy and pasted in cells is known as DNA replication. Before dividing, a cell must replicate its entire genetic code so that each resulting daughter cell has its own complete genome.

During DNA replication, each of the double helix's two strands serves as a template from which new strands are copied.

The new strand will work in tandem with the parental or "old" strand. Each new double strand is made up of one parental and one daughter strand.

Thus, the correct option is A.

The specimen pictured lived in south africa, was discovered by raymond dart in 1925, and was approximately 3 years old at time of death that fossil/species is Australopithecus africanus.

When the skull of this 3-year-old child was discovered in 1924, it was one of the first early human fossils discovered in Africa and the first early human fossil discovery to garner significant attention to this area as the birthplace of the human family tree. But it still took more than 20 years for scientists to acknowledge Africa's significance as a key region in the history of human evolution.

Researchers initially observed signs of early human upright, two-legged (bipedal) walking in the preserved anatomy of the Taung Child. The location of the Taung Child's foramen magnum, or the opening through which the spinal cord and the brain are connected, served as proof.This spinal cord opening is located near the front of the Taung Child's skull, which is a feature connected to bipedal movement. The foramen magnum of a four-legged ape is located at the back of the head to keep its eyes forward (and not down) when it moves, in contrast to a bipedal adaption that allows the head to balance atop the neck.

Answer:

Bacteria reproduce through budding.

Explanation:

Cell budding is a type of asexual reproduction that can occur in both eukaryotes and prokaryotes. Or in this case bacteria.

It can't be meiosis because bacteria don't reproduce sexually at all.

It can't be mitosis because bacteria have a single, circular DNA chromosome and no nucleus.

It can't be regeneration since that isn't a type of reproduction but the process of renewal, restoration, and tissue growth.

Answer:

Explanation:

Bacteria reproduce through a process called binary fission.

Binary fission is a type of asexual reproduction where a single parent cell divides into two identical daughter cells. The parent cell replicates its DNA, and then the cell membrane and cell wall begin to grow inward, eventually forming a new cell wall in the middle. The cell then splits into two separate cells, each with an identical copy of the parent cell's DNA. This process can occur rapidly, with some bacteria doubling their population every 20 minutes, allowing them to quickly colonize new environments and adapt to changing conditions.

Mitosis and meiosis are processes that occur in eukaryotic cells, not in prokaryotic cells like bacteria. Mitosis is the process by which eukaryotic cells divide and reproduce, resulting in two identical daughter cells. Meiosis is a type of cell division that occurs in eukaryotic cells that produces four genetically diverse daughter cells from a single parent cell.

In addition, Budding is a form of asexual reproduction where the parent cell grows a small outgrowth (bud) which eventually grows into a new organism. This is not a method of reproduction that bacteria use.

Dermal papillae are structures located in the upper layer of the dermis, just below the epidermis. They are responsible for several important functions, including the provision of fingerprints, the containment of blood vessels, and the creation of more basement membrane for adhering the epidermis.

Dermal papillae also contain sweat glands, but they are not responsible for keratin production. Additionally, the cells within the dermal papillae are always dividing, which helps to ensure the continuous growth and repair of the skin. Overall, dermal papillae are critical structures that play a vital role in the health and function of the skin.
Dermal papillae are essential structures in the skin. Three choices that describe or relate to dermal papillae are:

1. Provide for fingerprints: Dermal papillae contribute to the formation of unique ridges on the skin's surface, known as fingerprints, which improve grip and tactile sensitivity.

2. Contain blood vessels: These structures house blood vessels that supply nutrients and oxygen to the epidermis, maintaining skin health and promoting healing.

3. Create more basement membrane for adhering epidermis: Dermal papillae increase the surface area of the basement membrane, enhancing the adhesion between the epidermis and the underlying dermis for improved skin strength and stability.

RNA viruses called retroviruses have the reverse transcriptase enzyme inside of them.

RNA can be transformed into DNA by reverse transcriptase, which can then be incorporated into the chromosome of the host cell. An enzyme found in the genetic material of retroviruses called reverse transcriptase, also known as RNA-directed DNA polymerase, is responsible for facilitating the transcription of retrovirus RNA (ribonucleic acid) into DNA (deoxyribonucleic acid). The hybrid's RNA strand is then degraded by reverse transcriptase, also known as RNase H. Then, double-stranded DNA is created using the single-stranded DNA as a template (cDNA). Many different creatures, including viruses, bacteria, mammals, and plants, have been shown to have reverse transcriptases. As a result, complementary DNA is created when an RNA template is used to create DNA through reverse transcription.
