Populations of caribou show a cyclical fluctuation with predictable patterns in Norway. Reindeer populations are higher in the
southern regions in winter months while populations are higher in the northern regions in the summer months. Infer the cause of
these predictable changes for the Norwegian reindeer populations.
-))
A)
B)
C)
Reindeer migrate from north to south in the winter months to reach more
fertile feeding grounds. They migrate to the north in summer months.
The reindeer migrate from north to south in the summer months to reach
more fertile feeding grounds. They migrate to the north in winter months.
The reindeer populations migrate to an intermediate location in Norway to
mate and then diverge to the northernmost and southernmost regions to
avoid competition for food.
There are two species of reindeer in Norway. The northernmost species
reproduces in the winter, causing an increase in population size. The
southernmost species reproduces in the summer, causing an increase in
population size.

Answer:

is the site where lipids destined for other cellular compartments are manufactured.

Explanation:

This is because smooth endoplasmic recticulum is an organelles found in eukaryotic organisms that lack membrane bound ribosomes and are found in cells that has much lipids like ovaries, testes, oil glands in the skin e.t.c. They are important in the synthesis of lipids is the site where lipids , Phospholipids, steroid hormones.

They also play a major role in detoxification of harmful metabolic by products and metabolic processes of calcium ions within the cell

Taigas, tundras, and tropical rainforests have a lot of sunlight

It has low temperatures throughout the year. Winter is quite severe and summer is cold.

Also called coniferous forest due to the predominance of pine and spruce.

The vegetation is dense and forms strata, depending on the canopy cover of the trees, which gives rise to different microclimates. The vegetation also has epiphytes, lianas and lichens.

With this information, we can conclude that the tundra, taiga and tropical forest have in common the good disposition of sunlight. Correct answer C:a lot of sunlight.

Carbon is important in biology because without it, life itself would not exist. Carbon is important in everyday life for all living beings in order for them to live, grow, and reproduce. Carbon compounds are also very versatile and they are in many objects we use every day.

Carbon is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and organic compounds, scientists can learn more about life, the human body, and how it works. Organic Molecules Most organic molecules are made up of long rings or chains of carbon atoms with atoms of other elements attached.

The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun. Photosynthesis occurs in both land plants and ocean dwelling organisms like algae.

Carbon is the central element to all living organisms, it is key to producing electricity, and the sun needs carbon to produce energy. Therefore, option D is correct.

Because it is present in every biomolecule, carbon is regarded as the element of life. Carbon is a component of all vital biomolecules, including lipids, nucleic acids, proteins, and carbohydrates. The presence of four valence electrons in carbon makes it so distinctive.

The majority of the world's electricity comes from fossil fuels, which also make up the vast majority of the world's transportation fuels like gasoline and diesel. Energy is extracted from fossil fuels through the combustion of hydrocarbons.

Carbon, nitrogen, and oxygen processes convert hydrogen into helium but do not exhaust themselves, providing around 1% of the sun's energy. Hence, option D is correct.

Answer:

The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Variant copies of a gene are called alleles, and an individual's genotype is the sum of all the alleles inherited from the parents.

Explanation:

Answer: polygenic

Explanation:

Answer:

Fats and proteins that are present in liver, kidneys, and muscles.

Explanation:

When the reserve of glucose is used by the body during starvation, our body uses fats and proteins that are present in liver, kidneys, muscles etc and convert these fats and proteins into glucose. There is high amount of fats and proteins present in our body which can be used when the glucose reserves depleted from the body during starvation so we can conclude that the fats and proteins are the sources that can be used to produce glucose for the body.

Answer:

The correct answer would be - the 16S rRNA gene.

Explanation:

16S ribosomal RNA is a small subunit of ribosomes found in prokaryotic cells such as microbes. It is coded by the 16S rRNA gene that is used in constructing phylogenies again due to the slow rate of evolution.

This gene is suggested to be used as a molecular clock that is more reliable as it has sequences that show similar functionalities in distantly related bacterial lineages. It is the gene that produces protein more quickly than other bacteria.

Explanation:

The cell cycle is the most important process in the growth of an organism.

Explanation:

Cell cycle is the fundamental process by which a cell matures, synthesises DNA and divides to form daughter cells. Somatic cells divide regularly.

All multicellular organisms use cell division for growth, maintenance and repair of cells and tissues. Unicellular organisms use this process to reproduce.

Cell cycle affects our daily lives. Most cancers are a result of inappropriate cell division arising due to aberrations in normal cell cycle regulation. Stem cell biology and regulation in growth of organs also involves extensive study of cell cycle.

amphipathic, with at lest one hydrophobic region

Explanation:

For a protein to be an integral membrane protein it would have (C) :    amphipathic

Amphipathic is a chemical property of a protein molecule whereby it has both hydrophilic and hydrophobics portions in the its molecule. ( i.e. It contains water soluble and non-water soluble portions ) and for a protein to be an integral membrane it has to posses both water soluble and non-water soluble portions in its molecule.

Hence we can conclude that for a protein to be considered an integral membrane protein it will posses an Amphipathic  property.

Answer:

A. To store the genetic instructions needed to specify traits.

A chromosome is made of a strand of DNA that's encoded with genes.

Chromosomes have hereditary function that are capable of self-duplication and they have thread-like structures seen inside the nucleus of plant and animal. In plants, they go through a cycle called alteration of generation that has multicellular stages. One is sporophyte that is a diploid, and the other is gametophyte with a haploid.

Moreover, spores are produce through meiosis so it go through a process of chromosome reduction in order to create a haploid spores. While, gametes undergo mitosis and the structure is already a haploid, which means that the number of chromosomes will not change in order to produce haploid. In this case, the plant have both spores and gametes and the similarities is that, they are both singles celled and a haploid. Therefore, the number of the chromosome in the gametophyte generation is also 32.

Answer:

The correct answer is - a reduced expression of alpha, beta, and omega subunits of RNA polymerase.

Explanation:

Sigma subunit of RNA polymerase is the subunit that the holoenzyme, the other part of the enzyme, identifies and attaches with the specific DNA site called promotors that is responsible for coding the alpha, beta, and omega subunits of this enzyme.

As it is given that there is a deletion in the sigma subunit due to mutation that results in decreased the sigma factor's binding affinity to the promoter region. That ultimately leads to less or unable to bind properly to the promoter and the level of gene expression to fall or be reduced.
