Osteoblasts is cuboidal cells that make up 4-6% of all resident bone and are found along the surface of the bone. They are primarily recognized for their role in the formation of new bone.
Does the osteocyte keep the bone?Osteocytes behave as cells, secreting hormones that targeting distant organs like the kidney to control phosphate transport as well as local crystal deposition or chemistry at the level of the bone matrix. Numerous bone functions appear to be primarily localized by osteocytes.
How can osteocytes keep bone mass in tact?Even when they are dying, osteoclasts are recruited by osteoectoderms to help with bone regeneration, which helps osteoectoderms retain bone mass. The osteocyte expresses some, though not all, of the osteoblast's biochemical characteristics.

Parasitism is an interaction between two species in whichA.Both are harmedB.Both are benefitedC.One is benefited and the other is neither benefited nor harmedD.One is benefited and the other is harmed
Parasitism is an interaction between two species in which one species, the parasite, benefits while the other species, the host, is harmed. So the correct option is d.
In this type of interaction, the host provides the parasite with food, shelter, and other resources necessary for survival, while the parasite takes these resources without providing any benefit to the host. The host may suffer from decreased health, fertility, or survival, while the parasite may benefit from increased survival, reproduction, or access to resources.
This type of interaction is different from mutualism, where both species benefit, commensalism, where one species benefits and the other is neither benefited nor harmed, and predation, where one species benefits at the expense of the other's death. Parasitism is a widespread form of symbiosis in the natural world and it can take many forms.
For example, some parasites live on the surface of their host, while others live inside the host's body. Some parasites feed on the host's blood, while others feed on the host's tissues or organs. Some parasites are visible to the eye, while others are microscopic.

If you cross a red snapdragon with a white snapdragon what phenotype should you expect in 100% of the offspring if snapdragon flowers are expressed via incomplete dominance?
in snapdragon flowers, a heterozygous plant with one red allele and one white allele exhibits a pink phenotype.
Dominance has no impact on how an organism's genes are inherited; it only changes the phenotype that results from these genes. When the homozygous parent's phenotype cannot be distinguished from that of the heterozygote, complete dominance has taken place. But occasionally the heterozygote has a phenotype that is somewhere between the phenotypes of the two homozygote parents (one of which is homozygous dominant, and the other of which is homozygous recessive). This intermediate phenotype serves as an example of partial or insufficient dominance. A variety of phenotypes are typically seen in the progeny when partial dominance takes place. While the phenotypes of the offspring may vary, they will all fall within the homozygous parental phenotypes' range.
When homozygous red flowers (A1A1) and homozygous white flowers (A2A2) are crossed, a number of pink-hued phenotypes are produced. Although when two F1 pink flowers are crossed, both red and white flowers can be present in the offspring, it should be noted that partial dominance is not the same as blending inheritance. In other words, the inheritance of these alleles is identical; the only variation is in the way the alleles interact to produce phenotype.

what do we call specific sequences of genetic material that code for a trait
The fundamental unit of heredity in a live organism is a gene, which we refer to as precise sequences of genetic material that code for a trait.
The hereditary material in a cell is called genetic material. It contains all data particular to an organism. It is also known as RNA (ribonucleic acid) or DNA (deoxyribonucleic acid). DNA is found in prokaryotes like bacteria's cytoplasm. DNA is contained in the nucleus of the cell in eukaryotes, which include plants and animals, and to a lesser extent in extranuclear locations, such as the mitochondria (which contain mtDNA) and chloroplasts (containing cpDNA).
In the somatic cells of a multicellular creature, the genetic material, which regulates the organism's makeup, is similar. New cells inherit the same genetic makeup as their parent cells since the genetic material can reproduce along with the cell. Genes, gene segments, gene clusters, and even the full genome could be found in genetic material. Genes, RNA, and DNA make up the three different forms of genetic material.

While doing a pedigree analysis of a European royal family, you notice a disease in a female child of two healthy parents. There are also some cousins with the same genetic disease. If this disease is controlled by a single gene, then the most likely explanation for these observations is the disease is
A. only seen in heterozygous individuals such as the daughter. B. recessive and only seen in homozygous recessive individuals such as the daughter. C. dominant and is seen in homozygous dominant or heterozygous individuals. D. dominant and only seen in homozygous dominant individuals such as the daughter. E. a spontaneous mutation.
The most likely explanation for these observations is that the disease is recessive and only seen in homozygous recessive individuals such as the daughter. Here option B is the correct answer.
This is because the parents are both healthy and the disease is present in their daughter, which suggests that the daughter is homozygous recessive for the gene causing the disease. The presence of affected cousins also supports the idea that the disease is inherited in a recessive manner.

The more superficial cells of the epidermis become less viable and ultimately die. What two factors account for this natural demise of the epidermal cells?
The more superficial cells of the epidermis, also known as the squamous cells, become less viable and ultimately die due to two main factors: differentiation and desiccation.
Let us know briefly about them:
Differentiation: As the cells of the basal layer of the epidermis divide and migrate towards the surface, they undergo a process of differentiation where they lose their ability to divide and instead develop specific functions. The cells of the more superficial layers of the epidermis are fully differentiated and no longer have the ability to divide, making them less viable over time.Desiccation: The cells of the epidermis are constantly exposed to the environment and lose water through a process called desiccation. As the cells lose water, they become less plump and eventually lose their ability to function. The cells of the more superficial layers of the epidermis are also exposed to more environmental stressors such as UV radiation, which can damage the cells and further contribute to their demise.These two factors together account for the natural process of cell death in the epidermis, also known as cornification. It is a natural process that is constantly happening and being replaced by new cells, making the epidermis a continuously renewing organ.
