Answer:
The lipids and proteins that make up the membrane allow it to be selective about what enters and leaves the cell.
Explanation:
The cell membrane is a biological membrane that separates the interior of cells from the environment outside of it. This protects the cell from the environment outside of it. It also plays an important role in what gets in and out of the cell. As the membrane is made up of lipids and proteins, it is able to control the movement of substances in and out of cells and organelles.
Germ cells are haploid but gametes are diploid.
a. True
b. False
While gametes are diploid, germ-line cells are haploid. In prophase, I, independent assortment takes place. Homologous chromosomes' non-sister chromatids. Two chromatids, one on each of two homologous chromosomes.
What results in formation of diploid gamete?A germ cell splits into two portions during meiosis (reduced division), which leads to the formation of four gametes.
A diploid (i.e., containing coupled chromosomes) zygote is created during fertilization by uniting the male and female gametes.
Mitosis makes diploid offspring cells that are indistinguishable to the parent cell. Meiosis I is where the majority of the variations between mitosis and meiosis occur.
The homologous chromosomal pairs connect and are bonded together by the synaptonemal complex during meiosis I.
Therefore, it is true that Germ cells are haploid, but gametes are diploid.

a. Dissociate identity disorder
b. fugue
c. bipolar disorder
d. obsessive-compulsive disorder
Answer:
(c). bipolar disorder.
Explanation:
Manic-depressive disorder or bipolar disorder is a neurological disorder, characterized by unusual shifts in activity levels, mood, energy levels, and ability to perform daily life activities.
People affected with bipolar disorder experience depressive low episodes to manic high episodes. Depressive episodes are characterized by decreased energy and activity level, depression and thinking about death, while manic episodes are characterized by high energy and activity level and think about to do risky or worthless things.
Thus, the correct answer is option (c).

(a) compare interstitial and vacancy atomic mechanisms for diffusion. (b) cite two reasons why interstitial diffusion is normally more rapid than vacancy diffusion.
Interstitial and vacancy are two different diffusion mechanisms, with the former being typically faster due to the lighter mass of the diffusing species and the greater availability of interstitial sites for movement.
Explanation:(a) When comparing interstitial and vacancy diffusion mechanisms, the primary difference is in how atoms or molecules move from one location to another within a material. Interstitial diffusion occurs when the diffusing atoms or molecules move through the empty interstices in the crystal lattice. Conversely, vacancy diffusion requires a vacant lattice site or 'hole' to be near an atom; the atom can then jump into this void, leaving behind a new vacancy.
(b) There are two main reasons why interstitial diffusion is normally more rapid than vacancy diffusion. First, the mass of the diffusing species in interstitial diffusion tend to be lighter, allowing them to move faster. Second, interstitial sites are typically more available and require less activation energy to move into, compared to the energy required for an atom to leave its place and form a vacancy.
A drug is any chemical substance that alters the body physically or mentally for a ________ purpose.
Cyclones are formed due to
mist and snow
clouds and fog
warming of oceans
underwater earthquakes
Answer:
Correct answer is warming of oceans
Explanation:
when hot moist air flows at the upper surface of the ocean it tries to move in upward direction due to which less amount of air is left at the surface of ocean and hence a lower air pressure is created in this area.
surrounding air which is at higher air pressure try to push the low pressure air which rises the temperature of low pressure air and again this air moves upward leaving behind less air at the surface of the ocean.
when this high temperature and moist air moves in the upward direction it temperature decreases due to which clouds are formed . This combination of clouds and wind continuously grows and started spinning. When this combination of wind and clouds spin fast, that time an eye is formed at the center. At this center very low air pressure is there and air with high pressure flows down into this center.
In this way cyclones are formed.

An archipelago is a large group of islands. question 1 options:
a. True
b. False
Answer:
The statement is true
Explanation:
A large group of islands which are scattered closely in the body of water is called archipelago. The water body is usually oceans but it can be river and lakes. Volcano eruption is one of the main causes of making most of the island in an archipelago and these islands are called oceanic islands.
One of the example of archipelago is Finland’s Archipelago Sea which has more than 50,000 islands although many of them are so small that they do not measure even one acre. Therefore the statement is true.

What do chloroplasts look like under a microscope?
I depends, though “small greenish blob” would be a good description. The other answers contain great pictures of plant chloroplasts under a decent quality light microscope. However, plants (and algae) don’t all have the same size of chloroplasts and the chloroplasts can be very hard to see when they are small, not just because of size, be also because they appear less green (small size = less light absorption = less green in color).
If you use fluorescence microscopy, then the chloroplasts glow reddish-orange in color (very cool, especially when you have swimming algae).

What is moving a limb away from the midline of the body along the frontal plane called?
Abduction is the act of moving a limb away from the midline of the body along the frontal plane. This can be as simple as raising the arm or spreading fingers apart. The opposite movement, bringing the limb towards the body, is called adduction.
Explanation:The action of moving a limb away from the midline of the body along the frontal plane is called abduction. These motions occur within the coronal plane and involve medial-lateral movements. For example, when you raise your arm at the shoulder joint, moving it laterally away from the body, it is considered as abduction. Similarly, spreading the fingers or toes apart is also an example of abduction. Conversely, adduction is the movement that brings the limb towards the body or across the midline. The movements of abduction and adduction take place at joints like the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal.

Answer: Constructing dams, Building desalination plants.
A drought is a natural disaster that occur in a region that receives very low precipitation. The region exhibit desert like conditions such as hot and dry climate, compact and infertile soil, and scanty available water resources. Constructing dams can preserve the available water resource, it will also help in preserving the surrounding soil in maintaining the moisture content. If the available water is saline. Then the salinity can be removed by the desalination process and the water can be used.

What parts of a nucleotide make up the backbone of a nucleic acid?
Answer:
The correct answer would sugar and phosphate.
The nucleotide consists of three units; sugar (ribose in RNA and deoxyribose in DNA), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil).
The sugar group of one nucleotide is attached to sugar of another nucleotide with the help of phosphodiester bond.
Thus, alternate sugar and phosphate groups form the backbone of nucleic acid from which nitrogenous bases stick out.
After having harvested a wild turkey, what is the best and safest way to carry it out of the woods?
In order to carry the harvested turkey out of the woods, the hunter is always recommended to keep the bird in the hunter orange bag or cover it under the camouflage hunting vest.
Further Explanation:
The hunting of the turkeys is a very popular hunting program in many states. It is also posed as a dangerous activity as many turkey hunters have accidentally been shot during the hunting programs. The prime cause of this is the inability of the hunters to identify their target prior to shooting. This is because while turkey hunting the hunters are dressed in camouflaged dresses in order to hide and not recognized by the turkey and also to attract them. But in a way, the hunters also attract the other hunters who can recognize these hunters as the turkeys. Therefore, it is always suggested to never wear blue, black or white-colored vests as these colors match the feather of the turkeys.
Once a turkey is harvested, a hunter should be very careful while carrying it out of the woods. The bird must be concealed in an orange bag or hid under the camouflaged vest. The wings of the birds should not be hanging and the head must be covered entirely so as to not be displayed as a live bird by other hunters. The blaze orange garment is supposed to be worn by the hunters while traveling between the hunting sites in order to be identified by other hunters.
