How many chemical bonds can each carbon atom form?
Answer:
It has four valence electrons, which it can achieve a full outer energy level which forms four covalent bonds. When its bonds only with hydrogen, it forms compounds which is called hydrocarbons. Carbon can be form in single, double, or triple covalent bonds with other carbon atoms.
Explanation:
The valency of carbon is four. Therefore, carbon can form four chemical bonds.
What is a chemical bond?It is the attraction between two atoms, they share or exchange electrons to form molecules or compounds is known as a chemical bond. They share electrons to fulfill their valency. The number of bonds depends on the number of valencies.
There are three types of bonds and that are covalent, ionic, and metallic bond. A covalent bond or molecular bond is formed by sharing of electrons, it occurs in non-metals. Ionic bonds are formed by exchanging electrons, it occurs in both metal and non-metal. metallic bonds are present between two metals. The covalent bond is the strongest bond.
There are four valencies in carbon. Therefore, it can make four bonds.

Read the passage from Darwin's journal. sorry its so long
The Amblyrhynchus, a remarkable genus of , is confined to this archipelago; there are two species, resembling each other in general form, one being terrestrial and the other aquatic. This latter species (A. cristatus) was first characterized . . . from its short, broad head, and strong claws of equal length, that its habits of life would turn out very peculiar, and different from those of its nearest ally, the iguana. It is extremely common on all the islands throughout the group, and lives exclusively on the rocky sea-beaches, being never found . . . even ten yards in-shore. It is a hideous-looking creature of a dirty black colour, stupid, and sluggish in its movements. The usual length of a full-grown one is about a yard, but there are some even four feet long; a large one weighed twenty pounds: on the island of Albemarle, they seem to grow to a greater size than elsewhere. Their tails are flattened sideways, and all four feet partially webbed. They are occasionally seen some hundred yards from the shore, swimming about; and Captain Collnett, in his voyage says, “They go to sea in herds a-fishing, and sun themselves on the rocks; and may be called alligators in miniature.” It must not, however, be supposed that they live on fish. When in the water, this lizard swims with perfect ease and quickness, by a serpentine movement of its body and flattened tail—the legs being motionless and closely collapsed on its sides. A seaman on board sank one with a heavy weight attached to it, thinking thus to kill it directly, but when an hour afterwards, he drew up the line, it was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava, which everywhere from the coast. In such situations, a group of six or seven of these hideous reptiles may oftentimes be seen on the black rocks, a few feet above the surf, basking in the sun with outstretched legs.

During daylight savings, Christie's neighborhood soccer games get cut short because the sky becomes dark much earlier than during the summer. Her father talked to the electric company about installing large lights above the field so Christie and other kids in the community could continue their soccer games after dark. The electric company informed Christie's father that although the light poles could be installed, there are too many short trees and trees with low branches in the park to connect electrical lines. Without electricity delivered to the light poles, they would not work. Christie and her father talked about this information with neighborhood residents and together they came up with several ways to solve the problem.

Why do elderly persons often develop bowed back and appear to lose height?
Answer:
When we get older, we experience a loss of bone density and our bones begin to thin and become weaker, which results in osteoporosis, causing us to develop bowed backs and appear to lose height.
We lose bone density as we age, and our bones start to thin and weaken. This leads to osteoporosis, which makes us appear smaller and causes us to acquire bowed backs.
What is osteoporosis ?Osteoarthritis is an osseous disease that arises when the body makes either too little bone or loses too much bone. Like a result, bones deteriorate and are more prone to breaking from a trip or, in extreme circumstances, from tiny bumps or sneezes. Under a magnification, healthy bone resembles a honeycomb; the term "osteoporosis" refers to porous bone.
What is treatment of osteoporosis?Typically, bisphosphonates are used initially for treating osteoporosis. Among these is the when first tablet Alendronate (Fosamax). Weekly or monthly pills of was also (Actonel). Ibandronate (Boniva), a tablet taken every month or an IV infusion given every 3 years. The most accurate test for identifying osteoporosis and determining the risk of fracture is commonly believed to be bone density testing by DXA now at hip and spine.

1. HYPOTHESIZE: Some human activities change environments in ways that harm both people and other
organisms. Describe one example of this kind of activity.
Answer:
Deforestation is one major human activity that harms both people and organisms. Cutting down trees lowers Earths ability to create fresh air, which leads to more toxic and polluted areas that can cause problems with breathing and even lead to lung cancer. Deforestation can harm other organisms because many animals such as birds, squirrels, and owls, look to the trees for a habitat. However, as we destroy they can cause a decrease in population which leads to an even bigger problem in the food chain.

Which of the following means a hormone that aids in growth of gonads?
Glycogenesis
Thyrotoxic
Pancreatitis
Gonadotropin
Answer:
thyrootoxic
Explanation:
The hormone which aids in the growth of gonads is Gonadotropin. The correct option is gonadotropin.
Gonadotropins are defined as the hormones which play an important role in the growth and development of gonads. The gonads refer to the male and female reproductive organs, such as the testes and ovaries. Gonadotropins stimulate the production of sex hormones and even regulate the reproductive processes. These homones are essential for the normal functioning of the reproductive system.
Gonadotropins are classified as glycoprotein hormones which are secreted by gonadotropic cells of the anterior pituitary which is present in vertebrates.This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG),as well as at least two forms of fish gonadotropins.
Thus, the correct option is gonadotropin.

A. incomplete dominance.
B. codominance.
C. multiple alleles.
Inheritance of characters are based on Mendelian principle. According to it, the blending of phenotype is called incomplete dominance.
What is Mendelian principle?Gregor Mendel is known as father of modern genetics. For this Mendel performed experiment on pea plant.
The main principles of Mendelian genetics can be stated as follows:
Law of Independent assortment.Law of dominance.Law of segregation.When different alleles of parents blend to form a mixed colored organism, this is referred as incomplete dominance.

I
B.
Jessica inherited both genes from her mother,
C. Jessica inherited one recessive form of the
gene from each parent.
D.
Jessica inherited one dominant form of the
gene from each parent.
Answer:
D
Explanation:
Dominant and the recessive allele are the traits present in the genes that get inherited from the parent to their offspring.
The trait that is visible in the phenotype is called dominant while the trait that gets masked in the proximity of the dominant allele is called recessive.
The correct answer is:
Option C. Jessica inherited one recessive form of the gene from each parent.
This can be explained by :
The genotype of Jessica's eyes = bb (light)The genotype of her parents = Bb (dark eyes)See the attached image below for the cross:
The genes gets independently assorted and Jessica inherits the recessive form of the genes from both of her parent.
