Answer:
A. near-Earth objects.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
When scientists discuss objects that might hit Earth, the term which they use to describe them as a group is near-Earth objects.
A near-Earth objects can be defined as a small solar system body such as comets and asteroids whose orbit draws it close or in proximity to the earth's orbit due to the gravitational force of attraction of nearby planetary bodies.
Basically, if the closest approach of a planetary body to the Sun is less than 1.3 AU it is considered to be a near-Earth objects.
Hence, near-Earth objects may pose a collision danger to planet earth.

7. True or False. Transitional organisms are not actual species."
Answer:
False.
Explanation:
Transitional forms are species in their own right. They are called transitional forms because they possess traits, like fins, that are found in earlier fossil animals, but also possess traits, like limb bones, that are found in later fossil animals.

In humans, there is a dominant allele that causes vitiligo, where small-unpigmented spots appear on the body. Also, there is a recessive allele for another gene that caus- es albinism, which causes the entire body to be unpig- mented. Vitiligo cannot be seen in albinos. A man with vitiligo had an albino mother and normal father. If the man has a child by a phenotypically normal skinned woman who had an albino father, what is the probability of having a phenotypically normal child
Answer:
probability = 0
Explanation:
The probability of having a phenotypically normal child is = 0
This is because since the Paul has Vitiligo and the vitiligo ( allele ) is a dominant allele and hence the allele will be passed onto the Child ruling out the chance of the couple having a phenotypically normal child

Why did the plant you put in freshwater stay fresh?
Answer:
To maintain its turgor.
Explanation:
The plant you put in freshwater stay fresh because the plant maintain its turgidity. Plants used water in the process of photosynthesis for making their own food as well as maintain its turgidity. Every cell needs specific amount of water to remain turgor, if the water is lost from the cell or plant, the plant becomes wilted so that's why by putting the plant in freshwater remain fresh.

Des a magnetic field flows though the inside of a magnet
Answer:
Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.
Explanation:
Answer:
However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole. Thus the magnetic field lines form a closed loop and do not have any ends.

The _____ strand of the opened DNA is easily replicated, but the _____ strand must be replicated in pieces because of its orientation.
a. bottom; top
b. lagging; leading
c. leading; lagging
d. top; bottom
Answer:
c. leading; lagging
Explanation:
This question s describing the process of DNA replication, which is the process by which DNA forms an identical copy of itself. The process of DNA replication is carried out majorly by an enzyme called DNA polymerase. After which the double stranded DNA has been unwound by DNA helicase, two single strands results.
One of these strands runs in the 3'-5' direction called LEADING STRAND while the other runs in the 5'-3' direction called LAGGING STRAND. However, because replication by DNA polymerase proceeds in the 5'-3' direction, the LEADING strand of the opened DNA is easily replicated, but the LAGGING strand must be replicated in pieces called OKAZAKI FRAGMENTS because of its orientation.

How do the vacuoles and cytoplasm contribute to maintaining homeostasis in a cell?
Answer:
Vacuoles regulate the turgidity by regulating the amount of water inside the cell. cell has excessive water: vacuole absorbs the water and then diffuses it out of the cell. cell lacks water: water from the vacuole gets passed back into the cell thereby maintaining turgidity

If you wanted to study the effects of soil moisture and light intensity on the growth of soybeans and required a high ability to regulate these independent variables, what type of experiment would you choose?A. Laboratory experiment.
B. Field experiment.
C. Natural experiment.
D. Reference experiment.
Answer:
A
Explanation:
The correct answer would laboratory experiment.
In the laboratory, variables can be controlled as much as possible using relevant equipment unlike in natural habitats or field experiments. For example, the amount of water that each plant would receive can be measured using measuring cylinders and the time they are applied can also be fixed.
Field and natural experiments require that experimental procedures are carried out in the field under natural conditions. Consequently, variables such as the amount of moisture that gets into the soil or the amount of light a plant will receive will be extremely difficult to control. Precipitation time and the duration of light can also not be controlled.
The correct option is, therefore, A.
As a plant grows, new root hair cells are formed from unspecialised cells.
How does an unspecialised cell become a new root hair cell?
Answer:
Root hairs appear in the root maturation zone and differentiate from unspecialised cells called trichoblasts.
Explanation:
Root hair arises as a small protrusion surrounded by a cell wall, they are found in the piliferous area; they can originate in unspecialised epidermal cells, in some called trichoblasts. The bump begins to elongate and moves away from the epidermis, forming root hair. The root hairs as they lengthen, it is seen that their content shows a polarized distribution, the apical part is constituted mainly by vesicles secreted by the Golgi apparatus that contain the precursors of the cell wall that are to be released by exocytosis. Trichoblasts can be arranged in different ways, there are roots where any of the cells that are part of the rhizodermis can give rise to a root hair. In other roots, trichoblasts and atricoblasts have been seen to be distinguished alternately along a row of cells.
what two things can happen to the food made by plants?
Answer:
Food made by plants can get used by plants or by other animals as plants maybe eaten by other organisms that feed on plants by living on them, these organisms are called parasites. Or else the food can be used up by plants to carry out their metabolic activities ( activities at cellular level which keeps the plant alive ) like cellular respiration
Answer:
The food that is prepared by the plant is utilized for its metabolic processes, the excess food is stored in the form of starch, in the plants. ... The plants prepare starch by a process of photosynthesis with the sunlight along with "water and carbon dioxide
The food produced by the plants is in the form of sugar and the extra sugar produced is changed to starch and is stored in different parts of the plant such as in roots, stems, leaves, fruits and flowers.

Which of the following does not explain why if two people are exposed to the same high stress causing conditions, there is a likelihood that they will not be affected the same way? A) the two have different lifestyles B) some people are not at all affected by stress C) gene-environment interactions may affect the level of depression D) people react differently to stress E) presence of a specific gene variation
Answer:
Probably B
Explanation:
They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct.
