Answer: C. meiosis produces sex cells that are joined during sexual reproduction to produce offspring

Explanation:

Meiosis is also called as reduction division in this the parent diploid cell divides twice to produce four haploid daughter cells. The daughter cells so produce after cell division contain half the number of chromosomes then that of the parent cells. The germ cells in males and females divide twice or meiotic division occurs in them twice to produce four daughter haploid gamete cells that are sperms (male) and ovum (oocyte) (female). These male and female gametes fuse during sexual reproduction. The sperm fertilizes an ovum to produce zygote.

Answer:

Explanation:

Water Levels

For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water. If the water level gets too low, more concentrated urine is produced so that water is conserved.

Internal Temperatures

Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body. Rapid breathing can also help the body eliminate excess heat. Together, these responses to increased body temperature explain why you sweat, pant, and become red in the face when you exercise hard. (Heavy breathing during exercise is also one way the body gets more oxygen to your muscles, and gets rid of the extra carbon dioxide produced by the muscles.)

Conversely, if your body is too cold, blood vessels in the skin contract, and blood flow to the extremities (arms and legs) slows. Muscles contract and relax rapidly, which generates heat to keep you warm. The hair on your skin rises, trapping more air, which is a good insulator, near your skin. These responses to decreased body temperature explain why you shiver, get “goose bumps,” and have cold, pale extremities when you are cold.

Homeostasis of Ions

Body functions such as regulation of the heartbeat, contraction of muscles, activation of enzymes, and cellular communication require tightly regulated calcium levels. Normally, we get a lot of calcium from our diet. The small intestine absorbs calcium from digested food.

The endocrine system is the control center for regulating blood calcium homeostasis. The parathyroid and thyroid glands contain receptors that respond to levels of calcium in the blood. In this feedback system, blood calcium level is the variable, because it changes in response to the environment. Changes in blood calcium level have the following effects:

When blood calcium is low, the parathyroid gland secretes parathyroid hormone. This hormone causes effector organs (the kidneys and bones) to respond to increase calcium levels. The kidneys prevent calcium from being excreted in the urine. Osteoclasts in bones reabsorb bone tissue and release calcium.

When blood calcium levels are high, the thyroid gland releases calcitonin. Calcitonin causes the kidneys to reabsorb less calcium from the filtrate, allowing excess calcium to be removed from the body in urine. Calcitonin also suppresses the formation of active vitamin D in the kidneys; without vitamin D the small intestines don’t absorb as much dietary calcium. Osteoblasts, stimulated by calcitonin, use calcium in the blood to add to bone tissue.

Answer:

The correct answer would be - strontium, magnesium, beryllium.

Explanation:

As we know that the number of the same valence electrons is most likely to exhibit similar physical and chemical properties so the elements of the particular group in the periodic table have a similar number of physical and chemical properties and a similar number of the valence electrons.

For example, group 2 elements are known as alkaline earth metals, and strontium, magnesium, beryllium, and calcium are the same group elements thus, they have the same chemical and physical properties as they have 2 valence electrons.

Answer: Species can change over time in response to changes in environmental conditions through adaptation by natural selection acting over generations. ... Evolution results primarily from genetic variation of individuals in a species, competition for resources, and proliferation of organisms better able to survive and reproduce.

Answer:

the answer is S-G-S-G  

Explanation:

DNA helicases are enzymes that catalyze the unwinding of the double DNA helix in order to form a replication fork at the origin of replication (i.e., the site where DNA replication starts). DNA replication occurs in a bi-directional manner by two replication forks that move in opposite directions in order to form a replication bubble. The origin of replication is formed during the transition from mitosis to G1 when they are licensed for the subsequent S phase. The origin recognition complex (ORC) is a DNA binding complex that binds to the origin of replication, whose function is to act as a scaffold for the assembly of initiation factors. ORC is phosphorylated during the beginning of the S phase in order to dissociate this complex from chromatin.

Answer:

75% curly

25% straight

Explanation:

When two parents' heterozygous for genes for curly hair are crossed, 75% of their offspring would have curly hair, while 25% of their offspring would have straight hair.

Heterozygous may be defined as the presence of two different alleles at a particular locus. It always includes one normal allele and one mutated allele.

Here, the allele for curly hair is dominant over the allele for straight hair. So, the offspring who carry the pure dominant and heterozygous alleles for curly hair would have the phenotype of curly hair, while the offspring who carry both the recessive allele would have the phenotype of straight hair.

Therefore,  when two parents' heterozygous for genes for curly hair are crossed, 75% of their offspring would have curly hair, while 25% of their offspring would have straight hair.

Answer:

The correct answer is ''collect absorbed nutrients for metabolic processing in the liver.''

Explanation:

Portal circulation is called that system that is between two large capillary beds, represented by the gastrointestinal organs, pancreas and spleen on the one hand, and the liver on the other. Hence, any venous system of the organism that is located between two capillary territories is called "portal system".The hepatic portal vein collects the deoxygenated blood from the gastrointestinal system, spleen and pancreas, this blood is venous and comes deoxygenated, in addition to being loaded with the nutrients absorbed in the digestive process, so it is a blood subjected to a high overload, but that quickly, thanks to its distribution through the liver, it will be bypassed to various chemical processes to extract a large part of the nutrients from it, and purify and eliminate toxins.

The function of the hepatic portal circulation is to collect absorbed nutrients for metabolic processing in the liver. Therefore, option D is correct.

The hepatic portal system is also known as the hepatic portal circulation or portal venous system. It is a specialized network of blood vessels that carries blood from the gastrointestinal tract, spleen, and pancreas to the liver. It plays a crucial role in directing nutrient-rich blood from the digestive organs to the liver for processing, storage, and detoxification before it is distributed throughout the rest of the body.

The hepatic portal system allows the liver to regulate the composition of blood coming from the digestive organs before it enters general circulation. Thus, option D is correct.

Answer:

D. Same number of chromosomes as the original cell

Explanation:

Mitosis is a kind of cell division which results in two daughter cells that are genetically identical to one another and the parent cell. Mitotic division causes each daughter cell to contain the SAME NUMBER OF CHROMOSOMES as the parent cell.

For example, a somatic human cell contains 23 pairs of chromosomes. If this cell undergoes division by mitosis, the two daughter cells that will result will contain 23 pairs of chromosomes each. This means that the two new cells that results from mitosis have the same number of chromosomes as the original cell.
