Answer:
The correct answer is OPTION C (Circumduction)
Explanation:
Circumduction is motions without clear opposites of the part of the body, an example is rotating the hand from the wrist. The answer is circumduction because this type of movement ensures the distal end of a bone moves in a circle while the proximal end remains relatively stable is particularly found in bones where the movements of the joints are opposite to each other example is the ball and socket joint movement. For circumduction to take place, the degree of distance between two bones of the body has to be decreased and sometimes straightened to increase the level of movement or motion produced, there must be a movement towards the middle of the body and sometimes joint movement away from the middle of the body. All these movements are in order.
Indicate whether each statement is true or false. 1. Rod cells are depolarized in the dark. (Click to select) 2. Glutamate binds to receptors on bipolar cells and causes them to depolarize. (Click to select) 3. Light and dark adaptation are accomplished by changes in the amount of available iodopsin. (Click to select) 4. When light reactions occur, retinal is completely released from opsin. (Click to select)
Answer:
The correct answer is - 1. true, 2. true, 3. false, and 4. true.
Explanation:
1. Rod cells are the photoreceptors present in the retina that are hyperpolarized not depolarized in dark due to sodium ions efflux.
2. Depolarisation of the bipolar cell of the retina by glutamate release by rods and cones.
3. The adaption according to the light is known as a light adaptation which takes place due to a large part of photochemical in both rods and cones which is reduced to retinal and opsins.
4. when the light reaction takes place retinal converted to opsin
Rod cells are photo-receptors that present in the retina. They hyper-polarized in the dark due to sodium ions efflux. Statement 1, 2, and 4 are correct while statement 3 is incorrect
1) Rod cells are photo-receptors that present in the retina. They hyper-polarized in the dark due to sodium ions efflux.

Explanation:
All living things are characterized by their ability to grow, reproduce, use energy by respiration, respond to stimuli, and easily adapt to their environments. When a living thing loses the ability to perform all of these basic functions, then it can be said to be non-living, or dead.
In addition, locomotion, excretion, metabolism, and nutrition were all exhibited when dead things were once alive.

Answer:
1. deciduous trees lose their leaves seasonally and include trees such as elm and maple.
2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include pine and cedar.
3. evergreens are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar, and Mango.
Explanation:
Deciduous trees: These plant species lose their leaves every year during the cold and dry autumns and winters, as it is the most limiting period over the year. Foliage resprout again during the warmer wet season when it rains more often, during spring and summer. Template forest biome characterizes for having deciduous trees such as oaks, maple, or elm, among other phanerophyte species.1. deciduous trees lose their leaves seasonally and include trees such as elm and maple.
Conifer: Correspond to the gymnosperm group. They are perennial, vascular, evergreen, woody plants. They characterize for having a straight trunk with secondary growth and no vessels in the xylem tissue. Their branches usually develop horizontally, with needle-like leaves growing on them, unisexual flowers, and seeds included in a cone.
2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include pine and cedar.
Evergreens: Perennial plants that keep their green leaves the whole year. These are the opposite of the deciduous trees. Tropical forests characterized for having these broadleaf plant species, such as mango, that are favored by the environmental conditions as precipitations are abundant and the average temperature is elevated most of the year. Also, many evergreen plants are typical of the boreal forest. Pines, cypress, cedar, and sequoia are examples of these last ones.
3. evergreens are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar, and Mango.
Hardwoods: Angiosperms. Xylem with vessels. These species present a high diversity in shape, textures, and sizes. They might reproduce asexually or sexually by producing flowers, fruits, and seeds. Also, they might be either evergreen or deciduous.4. hardwoods reproduce using flowers and have broad leaves; hardwoods include trees such as Elm, Maple, and Mango.

How might environmental manipulation of a crop have unexpected consequences? a. The new crop may require more water than the original. b. The crop may harm the environment. c. The yield may be reduced. d. All of the above Please select the best answer from the choices provided
Answer:
D all of the above
Explanation:
just took the test
Environmental manipulation can have both types of consequences - beneficial as well as adverse. At times, these changes can be unexpected too. The correct option is D.
What negative effect does environmental manipulation of a crop have?The crop can have a need for more water as compared to the original if there would be a change in the soil, region or even climate of the crop. An increase in the temperature can affect the availability of water to the crop.
Changes in the soil can result in variation in the availability of minerals required for the growth of plants. This can cause improper health condition of the crop, which will ultimately decrease its yield.
Overuse of fertilizers and pesticides can affect the quality of the soil and also have a negative impact on the crop. It can also be passed on to the consumers of the crop due to bioaccumulation.
Thus, all of the mentioned statements are correct. Hence, the correct option is D.

What happened if we add normal saline instead of PBS during beta amylase extraction?
Answer:
hi
Explanation:
Saline is the solution of water and NaCl does not provide the appropriate pH, so enzyme activity is lost, we cannot add saline instead of PBS during beta amylase extraction.
How saline water affects beta amylase extraction?PBS (phosphate buffer solution) is a type of buffer that is suited for beta-amylase activity, which implies that when beta-amylase is extracted using buffer, the enzyme's chemical activity is kept.
When we utilize saline, which is a solution of water and NaCl, the pH of the solution is not acceptable, and the enzymes' chemical activity is destroyed.
As a result, for enzyme/protein extraction, we always employ a buffer solution, which maintains the ph for the proper functioning of an enzyme.
Therefore due to pH conditions enzyme lost activity, and normal saline water can not be used instead of PBS for extraction of beta-amylase.
