Diploid

Further explanation

Diploid is a term for a cell or individual that has cells with two sets of genomes. Each genome in a cell is paired with a homolog based on the length of the chromosome. Diploid cells are formed from the fertilization of haploid gamete cells. Haploid gamete cells fuse so that the chromosomes mix in one cell to form diploid cells. In sexual reproduction gametes produce offspring that carry genetic traits from the fusion of these gametes (commonly known as male gametes and female gametes) The number of haploid cell chromosomes is abbreviated (n), while diploid (2n) because it is a multiple of the basic chromosome set or female gametes. called euploid polyploid. The diploid cells can divide into other diploid cells through the process of mitosis and forming somatic structures. This can occur because the chromosomes replicate before the cell divides. Through mitosis the cell will maintain the set number of chromosomes so that the newly formed cell has the same number of chromosomes as the original cell chromosome.

Diploid cells can produce cells that are haploid by the process of meiosis to form gamete cells. These events continue to occur through the process of reproduction and fertilization to form a continuous cycle if the individual continues to grow and multiply.

Answer:

Diploid.

Explanation:

DNA is present in the genetic material of all the eukaryotic and prokaryotic organisms.The eukaryotic genome contains DNA wraps around the histone proteins. Multiple distinct chromosomes are present in the eukaryote genome.

The eukaryotic genome are generally linear structure with the two copies of each chromosome. This makes the eukaryotic genome as diploid structure.

Thus, the correct answer is option (1).

Scientists often classify organisms based on their ability to perform certain processes
Mrac [35]

A. Plants can make their own food using energy from the Sun.

Animals cannot make their own food.

Explanation:

An example of the physiological capabilities of plants is their ability to make food on their own using the energy from the sun and chemical substances in the environment, animals do not make their own food.

  • Physicological ability refers the body functions of an organism. It refers to the life biochemical processes a body is able to carry out based on its design.
  • Metabolism is a living function attributable to all life.
  • Organisms can either build up energy such as seen in plants during photosynthesis. This process is called anabolism.
  • Some other organisms, makes use of the energy in their own life process and this is a catabolic process.

What is meant by the term epistasis? Distinguish between epistasis and dominance. Do not use examples in answering this question
Sunny_sXe [5.5K]

Answer:

Epistasis is a phenomenon in Genetics in which mutations on one gene locus are dependent on the mutations on some other genes locus. In other words, the expression of a phenotype of one gene is dependent on the presence or absence of mutations on other gene.

Dominance is phenomenon in genes in which a particular genotype masks the expression of alternative genotype and expresses itself due to complete takeover over other.

What organs are being affected from dwarfism???? And how????
Alexandra [31]

Pituitary dwarfism is caused by problems arising from the pituitary gland. The pituitary gland, also called the hypophysis, is a gland at the base of the brain that produces many different hormones. This gland is divided into the anterior (front) and posterior (back) halves. The anterior pituitary produces six hormones: growth hormone, adrenocorticotropin (corticotropin), thyroid stimulating hormone (thyrotropin), prolactin, follicle stimulating hormone, and lutenizing hormone. The posterior pituitary gland only produces two hormones: antidiuretic hormone (vasopressin) and oxytocin.

The growth process begins in the lower part of the forebrain in a small organ called the hypothalamus. The hypothalamus releases hormones that regulate the production of other hormones. When the hypothalamus releases growth hormone-releasing hormone (GHRH), the anterior pituitary is stimulated to release growth hormone (GH). Growth hormone then acts on the liver and other tissues and stimulates them to secrete insulin-like growth factor-1 (IGF-1). IGF-1 directly promotes the development of bone and muscle, causing bones to grow in length, and muscles to increase protein synthesis (make more protein).

Since growth is a complex phenomenon, it may be slowed down or stopped by abnormalities arising at any point in the process. Thus, dwarfism can result if there is a deficiency in any of these hormones, if there is a failure in the receptor cells receiving the hormonal stimuli, or if the target cells are unable to respond.

At its most basic, pituitary dwarfism results from decreased production of hormones by the anterior pituitary. When none of the hormones of the anterior pituitary are adequately produced, this is called panhypopituitarism. A common form of pituitary dwarfism is due to deficiencies in the production of growth hormone (GH). When less GH than normal is produced during childhood, an individual's arms, legs, and other structures continue to develop in normal proportions, but at a decreased rate.

What is the primary function of the carbon cycle
wlad13 [49]

The carbon cycle maintains the balance between the organic remains and carbon dioxide. In this cycle the the incorporation of carbon dioxide inside the plants by photosynthesis occurs and it is returned to the atmosphere by the process of respiration as well as the decaying dead organisms.

Is there any type of ecological relationship between wolf and moose populations on Isle Royale? If not, explain why not. If so,
Cerrena [4.2K]

The Prey-Predator relationship is the type of ecological relationship between wolf and moose populations on Isle Royale.

<h3>What do you mean by Ecological relationship?</h3>

The Ecological relationship may be defined as the interaction between the members of one species with respect to the members of the other in response to food, shelter, and space.  

Moose are herbivores and the prey of wolfs. It is clearly seen in the graph that when the population of wolves increases, the number of moose decreases. It states that wolfs feed on moose.

Therefore, the Prey-Predator relationship is the type of ecological relationship between wolf and moose populations on Isle Royale.
