I need help with any question, thanks.

Answer:

a chromosome that links a pair os sister chromosome

Explanation:

each chromosome is made of two parallel strands called chromatids. and each pair of chromatids is connected at one point by a structure called centromere.

Answer:

is the constricted region of a chromosome that separates it into a short arm and along arm

or...is a specialized DNA sequence of a chromosome that links a pair of sister chromatids

Explanation:

during cell division , the chromosomes first replicate so that each daughter cell receives a complete set of chromosomes

Answer:

One increase in population and the other decrease.

Explanation:

The population of the rats having little larger teeth and longer claws increases as compared to those rats having small teeth and shorter claws because the rats can escape from their predators and survive in that environmental conditions. The population of rats  having small teeth and shorter claws extinct in the end due to no reproduction and preyed by the predators and dominated by the population of the rats having little larger teeth and longer claws due to their features.

Answer: paralogous

Explanation:

Paralogous genes are a class of homologous genes which are due to the duplication of gene, then this are refered to as paralogous.

Genes for the oxygen-carrying proteins hemoglobin and myoglobin descend from a common ancestor but act in very distinct ways today. They are referred to as paralogous.

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.

Answer:

Yes.

Explanation:

Yes, this type of genetic engineering should be pursued in order to avoid decrease in death through infections or diseases as well as increase the production of milk and meat of that animals. With this genetic engineering, organisms have high resistance to diseases which decrease the cost of antibiotics. The positive effect of this genetic engineering is the increase in the resistance that leads to good health as well as productivity of organism.

Answer:

1. Algae have a variety of adaptations that help them survive including body structures, defense mechanisms, as well as reproductive strategies. Some algae have holdfasts that attach to the sea floor and anchor them down much like roots of a plant. Many algae, such as Sargassum, have gas-filled structures called floats.

2. Algae and plants are like humans as they need food, nutrients and a good environ- ment to grow and survive. Algae make their own energy or food from the sun but they also need water, correct temperature and nutrients to grow. Algae live in water or damp environments

3. In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration

Answer:

Chytridiomycetes

Explanation:

Blastocladiomycetes were initially grouped under the phylum Chytridiomycetes within the fungi kingdom because the former also have flagellated spores just like the latter

The similarity in spores initially made scientists classify both groups as zoosporic fungi. However, DNA and structural analysis of the spores of the two groups showed that Blastocladiomycetes has no monophyletic relationship with Chytridiomycetes.

Answer:

Explanation:

Firstly, an autosomal dominant trait is a trait the becomes expressed in the presence of only one affected allele, which is the dominant allele. Freckles is said to be an autosomal dominant trait meaning that the presence of the dominant allele (F) makes a person have the condition.

According to this question, If two individuals that are heterozygous for freckles cross i.e. Ff × Ff, the following proportion of offsprings will be produced: FF, Ff, Ff and ff (see punnet square).

From the genotypic observation of the produced offsprings:

FF, Ff - possess freckles

ff - do not possess freckles

Since, 3 (FF, Ff and Ff) of 4 offsprings possess freckles, the percentage of offsprings expected to have the condition will be:

3/4 × 100 = 75%

[tex]{\bf{Ingestion:}}[/tex]: It is the process of taking in food.It involves taking in food through the mouth and eating it.

[tex]{\bf{Digestion:}}[/tex]: It is the breakdown of food into simpler, soluble form with the help of digestive juices made in the body.

[tex]{\bf{Absorption:}}[/tex]: In absorption, food in the soluble form passes into the body fluids such as blood.

[tex]{\bf{Assimilation:}}[/tex]: Assimilation is the process by which absorbed nutrients are utilized by the body.

[tex]{\bf{Egestion:}}[/tex]: It is the process of elimination of undigested solid parts of the food.

Food is taken in or [tex]\tt\bf\blue{ingested}[/tex] through the mouth.Digestion begins inside your mouth when you chew the food.

The water in your mouth is digestive juice called [tex]\tt\bf\blue{Saliva}[/tex]

 .

It is secreted by the three pairs of the [tex]\tt\bf\green{Salivary \: Glands}[/tex] in your mouth.

Chewing breaks down the food into small pieces and mixes it with saliva.This process is called [tex]\tt\bf\green{Mastification}[/tex]

After the food is swallowed, it slides down the pharynx into the [tex]\tt\bf\purple{Oesophagus}[/tex]

(foodpipe).

The oesophagus leads from your mouth to the stomach.It is made up of muscles.

These muscles gently push food down to your stomach in a wave like action called [tex]\tt\bf\red{Peristalsis}[/tex]

The digested food is then absorbed by the small intestine. Absorption of the food occurs through thousands of small finger-like projections in the inner wall of the small intestine.

These projections are known as [tex]\tt\bf\pink{Villi}[/tex] increse the surface area of absorption of digested food.

Each villus has a network of fine blood cappilaries close to the surface.

The food absorbed on the surface of the villus passes into the blood in tge cappilaries.

The food absorbed into the blood is transported to different parts of the body.It is used to provide energy and materials for growth and repair of the body tissues.This is the final stage of digestion and is known as [tex]\tt\bf\red{Assimilation}[/tex]

Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body's ability to fight disease. Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS.

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.

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.
