ayuda porfa :c
Answer:
La gestión del agua es importante ya que ayuda a determinar las expectativas futuras de riego. La gestión del agua es la gestión de los recursos hídricos bajo políticas y regulaciones establecidas. El agua, que alguna vez fue un recurso natural abundante, se está convirtiendo en un bien más valioso debido a las sequías y el uso excesivo.
Explanation:
La gestión de los recursos hídricos es un tema muy importante desde varios ángulos, como el desarrollo de masas de agua para el futuro, la protección de las masas de agua disponibles de la contaminación y la sobreexplotación y la prevención de disputas. Una cuestión primordial es el agua: su disponibilidad, calidad y gestión.

Behind your house, there's a gorgeous pond filled with frogs. You notice that the frogs behind Mr. Archer's house often have three legs. You start wondering if the fertilizer that Mr. Archer uses for his lawn is causing the deformities in the frogs. You collect 10 frogs and put the special fertilizer in their container (Group A). You put another 10 frogs and place them in a different container with just water (Group B). A week later, 7 out of 10 of the frogs in group A grew only three legs. The frogs in group B grew four legs.

explain what density is. How is it different from weight and mass?
Hey there! I'm happy to help!
Density is how much mass there is per amount of space. The formula for it is mass divided by the volume. How much mass is there per (per means divide) amount of space?
Think of it like a room in a house. If the room only has one person, it isn't going to be very dense with people because there is only one person in the entire room. If there were 100 people, it would be very crowded in that room and the whole room would weigh a lot more. If we make our room the size of a huge convention hall though, 100 people wouldn't make it very crowded,. and it would be less dense. So the amount of people (mass) and the size of the room (volume) affect density.
In that sense, density is kind of like how crowded a thing is.
A hollow watermelon has less density than one that isn't because a watermelon that isn't hollow has more substance inside of it (more mass).
Mass is a factor of density because it measures how much of something there is. It can be related to the people in the room.
Weight is mass but with gravitational influence. A watermelon in space is going to weigh less than a watermelon on Earth because in space there is no gravity and it is floating around, but it will still have the same density just like our room full of people would still be crowded even if the people weighed nothing and were floating around.
On Earth though, we measure mass with terms like pounds, kilograms, etc. We use the term mass over weight because it is more scientifically accurate when calculating density.

Which two elements in the list would bond together based on their ionic charges?
A. calcium and potassium
B. potassium and neon
C. potassium and iodine
D. calcium and neon
Answer:
It's C. Potassium and iodine
The two elements in the list that would bond together on their ionic charges is potassium and iodine. The correct option is C.
What is ionic bond?Ionic bond, also known as electrovalent bond, is a type of linkage formed in a chemical substance by the electrostatic attraction of ions with opposite charges.
When the valence (topmost layer) electrons of one atom are indefinitely transmitted to another, a bond is formed.
The complete transmission of valence electron(s) among both atoms is referred to as ionic bonding.
It is a chemical bond that produces two opposing ions. The metal loses electrons in ionic bonds to become a positively charged cation, meanwhile the nonmetal chooses to accept those electrons to become a negatively charged anion.
Ionic bonds are formed by potassium iodide (KI). Iodine and potassium have very divergent electronegativities.
Since ionic bonds form between atoms with a large difference in electronegativity, the two atoms would form an ionic bond.
Thus, the correct option is C.

Why does the pectoral girdle need to be flexible while the pelvic girdle needs to be rigid?
Answer:
Flexibility: pectoral girdle is more flexible-less ligaments, ball and socket joint is shallower
Security: pelvic girdle is more secure, deeper socket. there are more dislocated shoulders than dislocated hips
ability to bear weight: pelvic girdle can bear more weight-the pelvic girdle has bones that are fused (os coxa) and a joint with the sacrum. the pectoral girdle has a little bone called the clavicle connecting it to the body wall.
Explanation:
The pelvic gridle is rigid to protect internal organs and support body weight whereas pectoral gridle require to provide movement to upper limbs.
The girdles are part of the appendicular skeleton which is attached to upper limbs and lower limbs, The upper limbs attach to pectoral gridles and lower limbs attached to pelvic gridles.
1. The pectoral gridle:
connects your upper limbs to the bones along the axis of your body.The pectoral girdle has two bones clavicle, or collarbone and scapula, or shoulder blade.it has ball and socket joint that provide movement to the upper limb.2. The pelvic gridle:
made up of left and right coxal bones and sacrumattached to legs or lower limbs therefore, called hipbonessupports body weight and protect internal organsit is rigid needed to support the weight of the body.Thus, the correct answer is - The pelvic gridle is rigid to protect internal organs and support body weight whereas pectoral gridle require to provide movement to upper limbs.

Why do minerals that have the nonsilicate crystalline structure called closest packing have high density?
Answer:
The native elements of a nonsilicate crystal have very high densities because their crystal structures are based on the packing of atoms as close together as possible.
Iron deficiency is one of the most common nutritional deficiencies in premenopausal women. Iron is a vital part of hemoglobin, which carries oxygen to red blood cells. Why do you think premenopausal women need more iron than men of the same age?
Answer:Premenopausal women shed blood as part of menstruation every month, which lowers the level of iron in the body. So, they need more iron than men and are also at a greater risk for this nutritional deficiency.

You observe the growth of a group of plants that have been tipped over.
How will auxin influence cell growth in the roots of these plants?
Auxin will build up on the lower side of the root and inhibit cell growth.
Auxin will build up on the lower side of the root and stimulate cell growth.
Auxin will build up on the upper side of the root and inhibit cell growth.
Auxin will build up on the upper side of the root and stimulate cell growth.
Auxin is responsible for the growth of cells in the roots of plants. Auxin build up on the lower side of the root which inhibit the cell growth. Auxins have an inhibitory effect on primary root growth. Thus, the correct option is A.
What is Auxin?Auxin is a plant growth hormone, which promotes cell growth and elongation of the plant. In cell elongation, auxin alters the plant wall plasticity making it easier for the plant to grow upwards. Auxin also influences the rooting in the plant.
Auxins have an impact on the growth of roots. Auxins facilitate the initiation of roots in plants. These hormones induce both growth of root branching (root initiation) and roots that are pre-existing. They also play important role in the formation of the adventitious root.
Therefore, the correct option is A.

Explain the mechanism of water movement from the roots up the tree to the leaves
1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.
The samples that were loaded into each of the four lanes are as follows:
Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested
