Answer:
The correct answer is - intrasexual selection.
Explanation:
Intrasexual selection is the act of competing with other members of one's own sex for various reasons such as high status, mating, area, and many more as well as the evolutionary process responsible for this competition. The great examples of these are antlers of deers and big size showy feathers of the peacocks to attract their males.
Thus, the correct answer is - intrasexual selection.

Myoglobin levels are higher in Tibetans and other ethnic groups that live at high altitudes. Explain the benefit of higher myoglobin levels for individuals living at high altitudes.
Answers
Answer:
They are able to take up and store more oxygen in their muscles
Explanation:
According to Oxford dictionary, myoglobin is ''a red protein containing haem, which carries and stores oxygen in muscle cells. It is structurally similar to a subunit of haemoglobin.''
The fact that Tibetans have a high level of myoglobin implies that they are able to take up and store more oxygen in their muscles since myoglobin is involved in storage of oxygen in muscle cells. Hence elevated levels of myoglobins enables the muscle cells to work more effectively.

Hemophilia A is an X-linked recessive disorder. What is the probability that a son will have hemophilia if the parents are a normal man and a woman who is a carrier
Answers
Answer:
none
Explanation:
Because the four options are: XX XX Xx Xx. There will be a 50% chance of a carrier but no actual hemophilia.
The probability that the son will have hemophilia if the parents are a normal man and a woman who is a carrier is 50%. The correct option is C.
What is Hemophilia A?A deficiency in the blood clotting factor VIII results in hemophilia A, an inherited bleeding disorder. Lack of factor VIII prevents the blood from clotting effectively to stop bleeding.
Due to a rare disorder called hemophilia, the blood does not clot normally because it lacks enough blood-clotting proteins. If you have hemophilia, you may bleed more profusely and for a longer period of time than you would if your blood clots normally.
A pedigree can be used to trace the X-linked recessive disorder (Xh) hemophilia through the generations. This (D) had hemophilia and passed away as a result of complications. Hemophilia is a bleeding disorder that causes abnormal blood clotting, which lengthens the time it takes for an injury to bleed.
Therefore, the correct option is C, 50%.

Explanation:
Where does the egg receive its energy from?
options:
a. The ovum contains a large quantity of cytoplasm, which contains nutrients for the first days of development after fertilization. The cytoplasm of the ovum contains over 140 000 mitochondria to produce ATP required for growth.
b. The uterus contains over 140 000 mitochondria to produce ATP and supplies this to the egg for growth.
c. Similar to sperm it receives its energy from fructose through its path to the uterus.
d. The ovum contains a large quantity of fimbria, which contains nutrients for the first days of development after fertilization.
Answers
Answer:
Until attachment to the uterus, the developing organism is on its own. That means it needs to supply its own energy, so the cytoplasm of the human egg cell contains many energy-generating factories called mitochondria. Those mitochondria come only from the mother.

Excessive sugar intake is related to development of dental caries because
A. oral bacteria produce acids that dissolve tooth enamel when they metabolize sugars.
B. sugar leaches calcium and phosphorus out of teeth.
C. salivary amylase dissolves tooth enamel during carbohydrate digestion.
D. sugars make the saliva more alkaline, causing damage to tooth enamel.
Answers
Answer:
The correct answer is A.
Explanation:
Dental caries is a chronic dynamic disease or process that occurs in the tooth structure in contact with microbial deposits. Among the factors that favor the development of dental caries is the excessive consumption of simple sugars. The sugars consumed with the diet constitute the substrate of the oral microflora and initiate the process of cariogenesis. Streptococcus can ferment sugars in the diet to produce primarily lactic acid as the end product of metabolism. This lowers the pH and demineralizes tooth enamel. Cariogenic microorganisms are characterized because they are capable of transporting carbohydrates in competition with other microorganisms, which could be present in the plaque; the rapid fermentation capacity of this substrate made up of sugars and starch and its acidic capacity - acid products - and acidic acid - capable of performing various functions under conditions of extreme acidity. The marked decrease in pH will contribute to the demineralization of the tooth, favoring the appearance of carious lesions in hard tissues: enamel, dentin and cementum.
The nuclei (the structure inside a cell that contains DNA) of the cheek cells have been stained using a special dye so that they appear purple. What shape are they
Answers
Answer: Oval.
Explanation:
The nucleus of a cell is a membranous structure normally found in the center of eukaryotic cells and is where most of the cellular genetic material is found, organized in DNA molecules (deoxyribonucleic acid) associated with proteins such as histones, which make up the chromosomes.
The function of the nucleus is to maintain the integrity of the genes in the DNA and to regulate gene expression to control cellular activities. It then controls when DNA is transcribed into RNA (ribonucleic acid) and when it is exported to the cytoplasm to be translated into proteins.
The nucleus is composed of a nuclear envelope consisting of a double membrane that surrounds it, as well as pores that allow the passage of RNA for the regulation of gene expression.
The cells of the inner cheek are classified as non-keratinized stratified squamous epithelium. An epithelium is a tissue made up of joined cells that line the outer surface of the body and inner organs. Squamous cells are flat, scale-like, whereas stratified cells are arranged in multiple layers. Non-keratinized means that the cells constitute soft tissue found in the moist parts of our body, such as the mouth, stomach, among others. In a normal healthy cell, the nucleus is uniformly stained, oval in shape and smaller in relation to the cytoplasm.

what use are the descending branches of glacial plants to them?
Answers
Answer:
Explanation:
A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow under stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques, moraines, or fjords. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that forms on the surface of bodies of water.
