Polar bears have large paws so that their body weight spread our over more space on the ice.
Imagine then as snowshoes for a human. They keep you up =).
Hope that helps! =)
Answer:
<em>Food and shelter are the most likely limiting factors in this case.</em>
Explanation:
In a forest, the huge trees act as a source of shelter for the animals that live in that habitat. It protects the animals from the heat of the Sun and extreme cold conditions.
The tress in the forest are the primary source of food for almost all the organisms that live in the forest. Cutting down trees will lead to food scarcity for the animals which inhabit that forest. As a result, the animals will either have to migrate or they will become die due to lack of food.
Hence, food and shelter are the limiting factors in this case.
Question
Microarrays allow for
•a comparison of expression of different genes under different growth conditions.
• the analysis of global gene expression.
•the hybridization of cDNA (converted from mRNA with DNA affixed to a solid-state support.
• all of the above.
Answer:
• all of the above.
Explanation:
Microarray involves the collection and isolation of genetic samples (DNA) from a sample or tissue.
Microarray is composed of a large number of DNA material that is arrange sequentially for easy identification and use.
Microarray is used to compare the expressions of various types of genes that are growing under different conditions. It can also be used for analysis of genes globally.
Answer:
oxytocin
Explanation:
The pituitary gland is a small gland that divides into two distinct portions, the anterior and posterior lobes, and is located at the base of the brain.
The anterior pituitary, also known as the adenohypophysis, secretes six important peptide hormones, they are:
- The growth hormone;
- Adrenocorticotropin;
- The thyroid stimulating hormone;
- Prolactin;
- Two gonadotropic homons - FSH and LH;
Oxytocin is not a hormone produced by the anterior pituitary but by the posterior pituitary, which is known as the neurohypophysis.
In general, the warm to hot summers and relatively mild winters of the Mediterranean and humid subtropical climates are similar. More people live in humid subtropical regions, which are occasionally invaded by chilly air in the winter.
Overall, this region's winter temperatures are typically 10 to 20 degrees Fahrenheit cooler than those in Mediterranean regions.
Whether or whether the summers are hot or warm in a region with a Mediterranean climate determines the subcategory. In comparison to the dry summer heat of the Mediterranean climate zones, the summers in the humid subtropical zone are equally warm or hot, but they typically have significantly more humidity, resulting in sultry weather that generally feels more uncomfortable.
What is humidity?
The amount of water vapor in the air is known as humidity. The gaseous form of water, known as water vapor, is typically undetectable to the eye. The presence of precipitation, dew, or fog is predicted by the humidity.
The temperature and pressure of the system of interest affect humidity. In comparison to warm air, cool air has a higher relative humidity when the same amount of water vapor is present. The dew point is another relevant variable. As the temperature rises, more water vapor is required until saturation is reached. A parcel of air will eventually approach saturation as its temperature drops, without adding or losing water mass. A parcel of air can include a wide range of water vapor concentrations.
