Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible? (1 point)
O Metals have low electronegativity, so they are conductive because they pass charges easily.
OTwo metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
O The bonds can shift because valence electrons are held loosely and move freely.
O An attraction between a positive charge and a negative charge is created.
The correct answer is; Metals have low electronegativity, so they are conductive because they pass charges easily.
Metals are found towards the left hand side in the periodic table. They are known for their low electronegativity. Metals are electropositive. This means that they loose charges(electrons) easily.
A metallic bond is comprised of positively charged metallic ions and a sea of electrons.These electrons can move freely.
This sea of electrons are the charges that are responsible for the properties of metals such as high conductivity.

2.1explain the body's hormonal response to dehydration
Answer:
Vasopressin, a hormon is secreted by pituitary gland which is response to dehydration , causes kidney to excrete less water.
The body's hormonal response to the dehydration is the action of vasopressin in the kidney. The vasopressin decrease the work of the kidney and it leads to decrease the amount of water secreted by the kidney to save water in the body.
What is dehydration?Dehydration is a condition where there is less water present in the body. There are many reasons of dehydration, like drinking less water or diarrhea. All reactions of the body work by water. So loss of water severely affect the body.
The hormonal response to dehydration is the release of vasopressin by the pituitary gland of the body. The vasopressin saves water from the body to help body fighting with dehydration. It makes the kidney to filter less water.
Thus, the activation of vasopressin in the kidney causes the body's hormonal reaction to dehydration. Vasopressin lessens the kidney's workload, which causes a reduction in the amount of water the kidney secretes to conserve the body's water supply.

what is meant by photosynthesis
Answer:
Photosynthesis is a physio-chemical process by which green plants use light energy to drive the synthesis of organic compounds. It is an enzyme regulated anabolic process.
Explanation:
Answer:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
A student places a healthy potted plant and a plastic straw in a closet for two weeks. After two weeks, the student observes that the plant is wilted and brown, while the plastic straw remains the same. The student classifies the plant as living and the plastic straw as nonliving.
What criteria does the student use to classify the plant as living rather than nonliving?
Answer:
Plants need water and sun to create their food source, glucose. When the plant was left in the closet it didn't have access to the sun. One of the requirements of life is that all living things need energy/have a metabolism. Without food the plant eventually died.

In your own words, describe the role of the scientific method in scientific investigation.
The scientific method serves as a structured framework for conducting scientific investigations.
How does the scientific method shape investigative processes?The scientific method involves a series of steps, starting with observation and formulation of a research question. Researchers then formulate hypotheses, educated guesses about the outcomes of their experiments.
These hypotheses are tested through carefully designed experiments, allowing for the collection of empirical data. The collected data is then analyzed to draw meaningful conclusions. The scientific method promotes objectivity, consistency, and reproducibility in research, enabling scientists to build upon existing knowledge and refine their understanding of the natural world.

What is puberty?
Puberty is the time when your child moves through a series of significant, natural and healthy changes. These physical, psychological and emotional changes are a sign that your child is moving from childhood towards adulthood.
Changes in puberty include:
physical growth and development inside and outside children’s bodies
changes to children’s sexual organs
brain changes
social and emotional changes.
When does puberty start?
Puberty starts when changes in your child’s brain cause sex hormones to start being released from the gonads, which are the ovaries and testes.
This typically happens around 10-11 years for girls and around 11-12 years for boys.
But it’s normal for the start of puberty to range from 8-13 years in girls and 9-14 years in boys.
There’s no way of knowing exactly when your child will start puberty. Early changes in your child’s brain and hormone levels can’t be seen from the outside, so it’s easy to think that puberty hasn’t started.
Puberty can be completed in about 18 months, or it can take up to 5 years. This range is also completely normal.
Girls: key physical changes in puberty
In girls, these are the main external physical changes in puberty that you can expect.
Around 10-11 years
Breasts will start developing. This is the first visible sign that puberty is starting. It’s normal for the left and right breasts to grow at different speeds. It’s also common for the breasts to be a bit tender as they develop. If your child wants a bra, a soft crop top or sports bra can be a good first choice.
A growth spurt occurs. Some parts of the body – like the head, face and hands – might grow faster than limbs and torso. This might result in your child looking out of proportion for a while. On average, girls grow 5-20 cm. They usually stop growing at around 16-17 years.
The body shape will change. For example, a girl’s hips will widen.
The external genitals (vulva) and pubic hair will start to grow. Pubic hair will get darker and thicker over time.
Around 12-14 years (about two years after breast development starts)
Hair will start growing under the arms.
A clear or white discharge from the vagina starts several months before periods start. If the discharge bothers your child, you could suggest your child uses a panty liner. If your child says it’s itchy, painful or smelly, consult your GP.
Periods will usually start within 2 years of breast growth starting, but can take up to 4 years.
Boys: key physical changes in puberty
In boys, these are the main external physical changes in puberty that you can expect.
Around 11-12 years
The external genitals (penis, testes and scrotum) will start to grow. It’s normal for one testis to grow faster than the other. You can reassure your child that men’s testes usually aren’t the same size.
Pubic hair will start to grow. It will get darker and thicker over time.
Around 12-14 years
Your child will have a growth spurt. Your child will get taller and their chest and shoulders will get broader. Some parts of your child’s body – like their head, face and hands – might grow faster than their limbs and torso. This might result in your child looking out of proportion for a while. On average, boys grow 10-30 cm. They usually stop growing at around 18-20 years.
It’s common for boys to have minor breast development. If your child is worried by this, it might help your child to know it’s normal and usually goes away by itself. If it doesn’t go away or if the breasts seem to be growing a lot, consult your GP.
Around 13-15 years
Hair will start growing on other parts of your child’s body – under the arms, on the face and on the rest of the body. Leg and arm hair will thicken. Some young men will grow more body hair into their early 20s.
The hormone testosterone is produced, which stimulates the testes to produce sperm.
Your child might start having erections and ejaculating (releasing sperm). During this period, erections often happen for no reason at all. Just let your child know that this is normal and that people don’t usually notice. Ejaculation during sleep is often called a ‘wet dream’.
Around 14-15 years
The larynx (‘Adam’s apple’ or voice box) will become more obvious. Your child’s larynx will get larger and their voice will ‘break’, eventually becoming deeper. Some boys’ voices move from high to low and back again, even in one sentence.
Answer:
For girls, puberty typically occurs between the ages of nine and thirteen
For boys, puberty typically occurs between the ages of ten and fifteen.
An increase in hormones – estrogen and progesterone in girls and testosterone in boys – causes the changes that happen during puberty.
Explanation:
Amylose is a form of starch made up of α glucose monomers that are bound by 1– 4 linkages.
Describe how the molecule would be affected if the subcomponents were joined by 1–6 linkages instead.
Explain how this might affect the function of the resulting molecule.
Answer: Carbohydrates usually function as energy storage or structural materials, and are composed of monosaccharides (simple sugars). All monosaccharides have three carbon atoms with a carbonyl group attached to one of the carbons, and hydroxyl groups attached to the remaining two. Monosaccharides are the primary fuel for metabolic processes, so we need the monosaccharides in carbohydrates to fuel our metabolic processes, making it an important part of our diet. If the subcomponents were joined by 1-6 linkages instead of 1-4 linkages, it wouldn't be called amylose, it would change to glycogen, making it less soluble.
If the subcomponents of amylose were joined by 1-6 linkages instead of 1-4 linkages, the resulting molecule would have a branched structure instead of a linear one.
Amylose is a type of polysaccharide that is found in starch. It is made up of alpha glucose monomers that are joined together by alpha-1,4 glycosidic bonds.
If subcomponents were joined by 1-6 linkage if will result into a branched molecule named as Glycogen.
-The branched structure would make it easier for enzymes to break down the molecule, which could affect how quickly it is digested and how it is used for energy.
Therefore, the change in the linkage would result in a different structure and function of the molecule (glycogen) making it less soluble .
