Answer:
The correct answer is option D. they were part of the control group.
Explanation:
A control group is a group of subjects different from the other test subject as they did not get the independent variable's effect on them and separated from the rest of the experiment. This group of subjects is used to rule out any other explanation of the effect of the independent variable.
In this experiment, subjects that received a placebo injection are the control group as they did not expose to the mutated virus and there are the presence of antibodies in the blood.
Which of the following is true of pine rockland habitats?
Answer:
Dry habitat.
Explanation:
Pine rockland has a dry habitat due to their location on higher ground. Pine Rocklands, also known as the Pinelands which have a hard rocky ground, made up of limestone. Pine rockland is an endangered habitat because 98 percent of the original habitat is lost while only 2 percent is remaining. This is due to the increase in population so the human clears the area for building places.

Honey Bees have a much different social and reproductive structure as compared to humans.
With honey bees, the queen bee contains more chromosomes with 32 than her drones do at
16 chromosomes. If the queen bee is identified as a Diploid, how would the drones be
classified?
O Haploid
O Diploid
O Monosomy
O Trisomy
Answer:
Unlike the queen bee, which has 32 chromosomes, drones have half the chromosomal charge (n= 16), so they are considered haploid.
Explanation:
The system of determination of the sex in the bees —like in other insects— is called haplodiploidy, and consists of which the females of the species possess complete charge of chromosomes, whereas the males only possess half. This is what happens with the queen bee with 32 chromosomes, while drones only have 16 chromosomes, so they are considered haploid.
Additionally, as a characteristic of haplodiploidy, males only proceed from female gametes, so they can only contribute gametes to produce females of the species.
The other options are not correct because:
Drones, with half of the chromosomal charge, cannot be diploid. Monosomy and trisomy are defects in the distribution of chromosomes during meiosis, which imply one chromosome less or one chromosome more in the normal chromosome charge respectively.A 60kg person climbs stairs of total height of 20m in two minutes.calculate the power delivered.g:10ms

Explanation:
Point (-2,5), Slope = -4
Point-slope
Slope-intercept
Answer:
if the slope is -4 than the slope intercept form is y=-4x+13
Explanation:
this is because since you need to find the y-intercept you need to add 1 and add 4. 1 to the x values and 4 to the y values.
Answer:
y=mx+b = y=−4x−3
Point Slope = y−5=−4⋅(x+2)

Why do plant cells need chloroplasts?
Answer:
Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. In this respect they are similar to mitochondria, but are found only in plants and protista.

How do you think the body processes monosaccharides differently than polysaccharides? Would they take the same amount of time to digest and harvest energy?
Answer:
Polysaccharides from cell walls make up the fiber humans eat, while monosaccharides provide the sweetness in foods. As humans eat, chewing breaks down polysaccharides into smaller particles that eventually, through digestion, yield up the simple monosaccharides that can pass into the bloodstream.

Explanation:
what came first the chicken or the egg
Eggs were found to evolve for over a billion years ago whereas chicken have been found to evolve around for just over 10,000 years. Thus, it can be concluded that eggs came first followed by the chicken.
What is Evolution?Evolution can be defined as any net directional change or cumulative change in the characteristics or traits of an organism or populations over many generations in order to survive better in the surrounding environment.
Eggs come from chickens and chickens come from eggs. It is the ancient riddle. However, eggs are just the female sex cells which were supposed to have evolved more than a billion years ago, whereas chickens have been found to evolve around for just 10,000 years ago. Therefore, it can be said that the eggs have came first followed by chickens.
The amniotic eggs shows up to roughly 340 million or so years ago, and the first chickens evolving at around 58 thousand years ago at the earliest. Thus, eggs were around way before chickens even existed.

Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.
Answer/Explanation:
It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.
