How are the density and temperature of air related?

Biology

Answer:

Charles's Law states that temperature and volume are directly proportional, so as temperature goes up so does volume. ... So as volume goes up (with constant mass) density will lower. Therefore, as temperature goes up density goes down.

Density and Temperature of air are Inversely Proportional

According to Charles' Law, the temperature and volume of a gas are directly proportional. As one rises, so does the other. Because density is mass/volume, when temperature or volume increases, the density decreases.

Describe both innate and acquired immune systems and the importance of vaccines.
lbvjy [14]

Answer:

Innate immunity is a non-specific immune system which provides defence against any pathogenic microorganism in early stages. It includes physical barrier such as skin, chemical barriers such as saliva, tears, et cetera, phagocytic cells such as macrophages, et cetera.

Acquired immune system is the one which develops after exposure to pathogen or antigen. It is highly specific in nature. It includes B-lymphocytes and T-lymphocytes. It includes the production of antibodies.

Vaccines are used to develop acquired immunity in people. The process is termed as vaccination or immunisation. Heat-killed or weakened pathogen or antigen is inserted into a person after which a person develops antibodies and memory cells against that pathogen or disease. So, the immune system acts more vigorously against that pathogen in secondary infection.

Thus, a person becomes immunised.

Which type of tree with poisonous berries is often found in uk churchyards and has a starring role in the film "a monster calls"
Sliva [168]
It would be the yew tree.

Yew (Taxus baccata) is a typical tree of churchyards, where some are thought to be well beyond 1,000 years old. Poisonous yew trees were planted in churchyards by the farmers to make sure that their animals didn’t stray into them. "<span>They stop and sleep under the yew tree (the monster), but in the morning, the young woman is dead, having been murdered, and the shocked young prince is covered in blood."</span>

Do some cows some (acquire/inherit) traits that make them have more muscles compared to other cows.
just olya [345]

Answer:

Explanation:

Molecular biology has enabled the identification of the mechanisms whereby inactive myostatin increases skeletal muscle growth in double-muscled (DM) animals. Myostatin is a secreted growth differentiation factor belonging to the transforming growth factor-β superfamily. Mutations make the myostatin gene inactive, resulting in muscle hypertrophy. The relationship between the different characteristics of DM cattle are defined with possible consequences for livestock husbandry. The extremely high carcass yield of DM animals coincides with a reduction in the size of most vital organs. As a consequence, DM animals may be more susceptible to respiratory disease, urolithiasis, lameness, nutritional stress, heat stress and dystocia, resulting in a lower robustness. Their feed intake capacity is reduced, necessitating a diet with a greater nutrient density. The modified myofiber type is responsible for a lower capillary density, and it induces a more glycolytic metabolism. There are associated changes for the living animal and post-mortem metabolism alterations, requiring appropriate slaughter conditions to maintain a high meat quality. Intramuscular fat content is low, and it is characterized by more unsaturated fatty acids, providing healthier meat for the consumer. It may not always be easy to find a balance between the different disciplines underlying the livestock husbandry of DM animals to realize a good performance and health and meat quality.
