Ba-1 what should sportsman always consider when hunting from a boat

1 answer:

4 0

Before going on a boat, the sportsman should consider that most of the accidents occurs when the boats are smaller in size. When the size of the boat is less than 16 feet, it is more prone to capsizing, especially the open boats.

This type of accident can even take place, when the conditions seems to be ideal. So, one should always keep in minds that open boats smaller than 16 feet are more prone to accidents.

A hypothesis is a general principle or explanation that is derived from observations. Suppose you make the following observation

mr_godi [17]

Question continued

For each statement below, mark "True" if it would be a valid hypothesis, based on these three observations alone, and mark "False" if it would not be a valid hypothesis.

1. The onion cells I looked at have a nucleus.

2. All onion cells have a nucleus.

3. All cells have a nucleus.

4. Some cells have a nucleus.

5. Only onion cells have a nucleus.

6. If I look at 10 skin cells from my hand, each one will have a nucleus.

Answer:

1. The onion cells I looked at have a nucleus. false - this is not a hypothesis, it is an observation of the evidence you collected.

2. All onion cells have a nucleus. true - this is a valid hypothesis based on the evidence you have gathered from looking at onions

3. All cells have a nucleus. true - this is a hypothesis based on you looking at 3 cell types, several samples of each, and finding that they all have a nucleus

4. Some cells have a nucleus. false - this is not a valid hypothesis. Your evidence so far suggests all cells have a nucleus

5. Only onion cells have a nucleus. - false, you know this to be false as other cell types you analysed had a nucleus

6. If I look at 10 skin cells from my hand, each one will have a nucleus. false - a hypothesis is supposed to be a general principle that is backed up by evidence, this is too specific.

Drag the labels to show how the glucose and hormone levels will change in each mouse after they are joined by parabiosis. labels

babunello [35]

<span>Answer: Parabiosis is an effective way to evaluate hormone function because it permits the exchange of only long-lived molecules (such as hormones) between the two joined individuals. Thus, the glucose levels of each mouse will stay the same, but the hormone levels will not. The db mutant's hormone level will decrease, and the wild type's hormone level will increase. Coleman's goal was to determine if the ob and db genes function in the hormonal regulation of appetite and body fat. In this experiment, if both appetite-suppressing hormone and glucose were exchanged, it would be impossible to determine whether any weight changes in the mice were caused by the transfer of hormone or the transfer of glucose from one mouse to the other. For example, an increase in hormone level (and thus greater appetite suppression) could lead to weight loss, as could a decrease in glucose level. On the other hand, a decrease in hormone level or an increase in glucose level could lead to weight gain.</span>

A cell biologist carefully measured the quantity of DNA in grasshopper cells growing in cell culture. Cells examined during the

xz_007 [3.2K]

Answer:

100 units

Explanation:

The interphase of the cell cycle includes three stages: G1, S, and G2. During the S phase of interphase, the cell enters the process of DNA replication. DNA replication duplicates the existing DNA molecule and doubles the DNA content of the cell. The cell accommodates the newly formed DNA in two sister chromatids of chromosomes. If a cell of grasshopper contained 200 units of DNA in the G2 phase, the cell would have 100 units of DNA in the G1 phase. The S phase would have doubled the DNA content and the G2 phase had 200 units.
