Answer:
The same group; hydrogen.
Explanation:
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Hence, valence electrons is same number for all elements in the same group of the periodic table (with the exception of hydrogen).
Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.
Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.
Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.
However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.

For the situation below , determine whether the premium will likely increase , decrease, or remain the same. Jamie just turned 25
Answer:
The premium decreases when Jamie turns 25 years old.
Explanation:
The question above is about auto insurance premiums, which, as the name already says, is insurance aimed at automobiles, with the objective of promoting economic and financial protection in relation to accidents and problems that may happen in these vehicles.
When an individual turns 25, like Jamie, the insurance premium decreases in value, that is, the insurance companies offered cheaper and more economical rates to the driver when he is going to renew the contract.

explain what is crossing-over in your own words
Explanation:
it occurs during meiosis. Its the exchange of chromosome pieces between the non-sister chromatids during the production of gametes.
Answer:
Crossing-Over is a DNA segment on each chromosome section may code for eye color, although one chromosome may code for brown eyes and the other for blue eyes. Crossing over occurs most often between different alleles coding for the same gene.

Explanation:
any resorse necessary to the survival of populations in an ecosystem may become a what?
Answer:
Limiting factor.
Explanation:
If the resource is necessary to the survival of a population and is needed to sustain it and allow the population to grow, it is a limiting factor. Simply put, limiting factors are defined as anything that constrains a population's size and slows or stops it from growing. Over use of resources can cause the species that need it to survive to die out and possibly become extinct if they can only be found in that ecosystem.
It is not a Biotic factor because biotic factors are described as a living organism that shapes its environment. These can include plants like algae.
An abiotic factor is a non-living part of an ecosystem that shapes its environment.
Both of these are defined as factors in an ecosystem and are important. HOWEVER, the question is asking about resources in an ecosystem. Therefore Limiting factor is correct.

What is not true about Longitudinal waves?
A. High Pitched sounds have higher frequencies?
B. Longitudinal must travel through a medium ?
C. Electromagnetic waves are Longitudinal waves?
D. sound of waves are Longitudinal waves ?
Answer:
I think B
Explanation:
Hope it helps! Correct me if I am wrong :>
Longitudinal must travel through a medium is not true about Longitudinal waves.
What is Longitudinal waves?
Wave that advances in the same direction as a periodic disturbance or vibration is referred to as a longitudinal wave. A point on any coil of the spring will move with the wave and return along the same path, passing through the neutral position and then reversing its motion once more.
A coiled spring that is compressed at one end and then released experiences a wave of compression that travels its length followed by a stretching. In addition to compressing and rarefying the gas in the direction of the sound wave's path, sound waves traveling through air also cause them to vibrate back and forth.
Seismic waves in the P (primary) phase are longitudinal as well. Each particle of matter vibrates about its usual rest position in a longitudinal wave.
Therefore, Longitudinal must travel through a medium is not true about Longitudinal waves.

You encounter someone who has never heard of evolution, and they ask you about a population of ducks that live in their grandmothers pond. They tell you that 10 years ago the pong had both large eyed ducks and small eyed ducks. But one day 2 of the large eyed ducks were killed by some wild dogs. Now, the population of ducks has entirely small eyed. Identify the mechanism of change in the duck scenario and use it as evidence to explain evaluation to that person.
Answer:
The large eyed ducks had an undesirable trait, but the small eyed ducks have a desirable trait. Because the large eyed ducks had a trait that decreases their chances of survival, they wete killed. But small eyed ducks are lucky because they have a trait that increases their chance of survival. The small eyed ducks reproduce more offspring that have small eyes, but the large eyed ducks cannot because they didn't survive. This causes that the allele for large eyes in the gene pool to decrease.

why we are saying it as carbaminohemoglobin not carboxyhemoglobin???
that carboxyhemoglobin is (protein) the stable complex of carbon monoxide with hemoglobin; it prevents the normal complexing with oxygen and thus leads to anoxia while carbaminohemoglobin is a compound of haemoglobin and carbon dioxide, one of the forms in which carbon dioxide exists in the blood.
Well, this is what I know from school but if you have any questions about this feel free to ask!!

What are the common stereotypes about the masculinity?
Answer: The Joker is a very popular character with boys, perhaps because laughter is part of their own “mask of masculinity.” A potential negative consequence of this stereotype is the assumption that boys and men should not be serious or emotional. However, researchers have also argued that humorous roles can be used to expand definitions of masculinity.
The Jock is always willing to “compromise his own long-term health; he must fight other men when necessary; he must avoid being soft; and he must be aggressive.” By demonstrating his power and strength, the jock wins the approval of other men and the adoration of women.
The Strong Silent Type focuses on “being in charge, acting decisively, containing emotion, and succeeding with women.” This stereotype reinforces the assumption that men and boys should always be in control, and that talking about one’s feelings is a sign of weakness.
The Big Shot is defined by his professional status. He is the “epitome of success, embodying the characteristics and acquiring the possessions that society deems valuable.” This stereotype suggests that a real man must be economically powerful and socially successful.
The Action Hero is “strong, but not necessarily silent. He is often angry. Above all, he is aggressive in the extreme and, increasingly over the past several decades, he engages in violent behavior.”
The Buffoon commonly appears as a bungling father figure in TV ads and sitcoms. Usually well-intentioned and light-hearted, these characters range from slightly inept to completely hopeless when it comes to parenting their children or dealing with domestic (or workplace) issues.

A plant cell can be distinguished from an animal cell because of the presence of?
Answer:
Well a plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles.
Explanation:
Hi there!
[tex]\large\boxed{\text{A cell wall and chloroplasts.}}[/tex]
Plant cells contain a cell wall which causes them to be more rigid in structure, whereas animal cells only contain a cell membrane.
In addition, plants contain chloroplasts, an organelle that allows the cells to undergo photosynthesis to produce energy. Animal cells, on the other hand, only contain mitochondria for cellular respiration.
