Bears are living so they are biosphere while the rocks they and Are interacting with are geosphere so it’s biosphere interacting with geosphere hence, D because two spheres interact and gravity isn’t a sphere water is interacting with hydrosphere which arent different so tis basically hydrosphere with hydro and lions use energy is just biosphere with biosphere and last one makes sense cuz it’s two different bio and geo!

A researcher has developed two stains for use with seed plants. One stains sporophyte tissue blue; the other stains gametophyte
sukhopar [10]

Answer:

A) The pollen grains will be pure red.

Explanation:

Plants have alternation of generations, this means that there are two different stages in their life-cycle: a sexual haploid (n) phase and an asexual diploid phase (2n). These phases occur in different individuals, so there is an haploid plant called gametophyte that carries gametes and after fecundation, it will rise a diploid sporophyte (asexual).  

In seed plants, the sporophyte is the plant that we normally see, and the gametophyte is reduced into an organ of the sporophyte. The male gametophyte is the pollen that is produced in the sporangium in anthers (parts of sporophyte).  When a pollen grain fecundes a female gametophyte (egg), it will produce a diploid embryo or new sporophyte.

Therefore, if the researcher exposes pollen to both stains, these grain will stain red, because red stain identifies gametophyte tissue.

Question 1 (Multiple Choice)
choli [55]
1. A forensic pathologist would most likely perform a forensic autospy. Forensic pathologists focus on cause of death by examining a bod or corpse. They perform postmortem examinations. 

2. Insect activity will begin immediately if a body is left in the open. That is why insect activity can help investigations with determining certain things such as time of death, where the person died and the like. 

3. A light meal will digest in about 1-2 hours. Digestion rates can give useful information about when a person had died. Medium meals take about 3-4 hours to digest and heavier meals take about 6 hours. 

4. Indicative acts are actions or behaviors that may or may not have taken place before someone dies. Indicative is suggestive, so it may or may have happened. When you say indicative acts you are referring to what may have happened (or may not) based on certain circumstances, observations or evidence.

State two ways in which endocrine glands and exocrine glands differ.
denis-greek [22]

Answer:

The two major differences lies in the function and support system.

Explanation:

The two major differences between an endocrine and an exocrine system are as follows –  

a) An endocrine system releases its produce (hormones) into the connective tissue i.e blood while the exocrine system releases hormones directly into the ducts so that it could reach the targeted tissue directly.  

For example – the Adrenal gland is an endocrine gland that secretes adrenaline directly into the blood. The salivary gland is an exocrine gland that releases its produce into the collecting duct leading to mouth. However, Pancreas is both endocrine and exocrine gland.

b) The endocrine system cannot work alone therefore it works in coordination with the nervous system to control actions and balance the body. However, the exocrine system works independently
