Answer:
A pedigree chart tracks inherited traits from parents to offspring.
Explanation:
A pedigree chart simply tracks inherited traits from parents to offspring. It is used to establish the genetic relationships between parents and their progeny.
Based on the available evidence, the chart walks through the genetic records of a family line. Parents and offspring's genetic history can be established by the chart. The chart is then further used to make predictions about genetic patterns for the family.Answer:

Chicken liver is placed into lemon juice for 10 minutes. What type of evidence of a chemical reaction would be expected to occur when H2O2 (hydrogen peroxide) were added?
A) a lot of bubbles within a few seconds
B) some bubbles within the first minute
C) very few to no bubbles
D) the liver will catch fire, explote and cause the school to evacuate.
Answer:
When hydrogen peroxide is added to a chicken liver sample exposed to lemon juice the chemical reaction will be slower and appear some bubbles within the first minute (option B).
Explanation:
The liver contains an enzyme called catalase, whose function is the degradation of hydrogen peroxide (H₂O₂), an intense reaction that produces gas and heat. The activity of this enzyme must occur at an appropriate pH, so changes in pH can affect the activity of catalase.
Under normal conditions, when a liver sample is exposed to H₂O₂, bubbles and foam appear in the sample as a result of the catalase reaction. When the chicken liver sample is subjected to the acidic lemon juice, the reaction will occur, but more slowly.This is because the activity of the catalase enzyme, present in the liver, continues to occur —although it decreases— and will form few bubbles over a longer period of time.
The other options are not correct because:
A. At a lower pH, the reaction will not form many bubbles.
C. Even if the reaction is minor, and produces very few enzymes, it will always occur.
D. Although the catalase/H2O2 reaction produces heat, it is impossible for the liver to catch fire and cause evacuation from the school, even less so with a reaction whose speed has been slowed down.

An atom of element x has one more shell of electrons than an atom of beryllium, but It
has one less valence Electron than beryllium.Which element is element X
Answer:
Sodium
Explanation:
This would leave you with 3 shells of 2, 8, and 1. Since it has one more shell then the second shell has to be 8. Since the first shell can only contain up to 2 it must be 2/8. And since it has one less valence electron than beryllium it must be a config of 2/8 1, which is the electron config of Sodium, Element with Atomic number 11 and electron shell of 2/8 1.
Answer:
Sodium

Which statements about kinetic energy are true? It's always transformed into potential energy. It's always associated with motion It can be transferred from one object or body to another. It's found only in objects moving in a straight line.
Answer:
It's always associated with motion
It can be transferred from one object or body to another
Explanation:
Kinetic energy is the energy due to motion of a body.
Moving objects possess kinetic energy which is resident in that body. As with other forms of energy, it can be transferred from one body to another. Kinetic energy can express itself as thermal energy, electrical energy, mechanical energy etc.. As a body moves, the kinetic energy is increases.If you were to look at a mass of cells under the microscope in which part of the cell cycle would you expect to find most of the cells?
a. interphase
b. anaphase
c. prophase
d. telophase
Answer:
A?
I think I'm wrong! please tell me what one it is if I'm wrong.
Answer:
A. Interphase
Explanation:
Because interphase is the phase of the cell cycle wherein most cells spend most of their lives.
A 320 N force is applied to a 16 kg box. What is the acceleration of the box?
Answer:
a = 20 m/s^2
Explanation:
F = m*a --> a = F/m = 320/16 = 20 m/s^2
Albinism is a recessive genetic condition in which a person lacks pigment that gives color to the skin. If the allele for albinism is represented as "a," and the functional allele is represented as "A," what will be the genotype of a person with albinism?
Answer:
The correct answer would be - "aa".
Explanation:
Albinism is an autosomal recessive genetic condition which means it will be expressed only if both alleles for the pigmentation are recessive. If a single copy of the dominant allele present with the recessive allele the expression of the recessive allele would be masked by it and skin will be pigmented however they will act as carriers of the condition.
There would be three condition or three allele combination:
AA - no recessive allele so no albinism
Aa - dominant allele with recessive allele which means carrier but pigmented skin
aa - both alleles are recessive so the albinism will be expressed.

Explain positive climate feedback and negative climate feedback
Climate feedbacks: processes that can either amplify or diminish the effects of climate forcings. A feedback that increases an initial warming is called a "positive feedback." A feedback that reduces an initial warming is a "negative feedback."

Climate feedback: processes that can either amplify or diminish the effects of climate forcings.
Explanation:
A positive feedback accelerates a temperature rise, whereas a negative feedback decelerates it.

lipids
nucleic acids
с
d
Answer:
nucleic acids
Explanation:
The macromolecule Astrid would be studying is the nucleic acids. They contain the genetic materials that would provide useful information for her study.
Nucleic materials are very essential to all life forms. In the broad sense, nuclei materials is the general term for DNA and RNA. These materials contains genetic information that can help Astrid's study. The materials are passed from parents to offspring in the genetic tree.Lizard scale coloration has a complete dominance relationship where green scales are dominant to blue scales.

50N of force is applied to a kg box. What will the acceleration be
[tex]\huge\boxed{50\frac{m}{s^-2}}[/tex]
_____________________________________DATA:
Force = 50N
Mass of the Body = 1kg
Acceleration = ?
_____________________________________SOLUTION:By the second law of newton,
F = ma
Rearrange the equation,
a = [tex]\frac{F}{m}[/tex]
Substitute the variables in the equation,
a = [tex]\frac{50}{1}[/tex]
OR,
a = 50 m/s^2

In what way is binary fission different from mitosis?
Binary fission is asexual reproduction where singled cell organisms copies of themselves. Mitosis is cell division that a cell and results in two newly formed cells that are identical. Binary fission is making copies of a cell, and mitosis is splitting a cell into two new indetical new ones.
Answer:
Explanation:
Mitosis is a type of cell division that takes place among non-sex cells (somatic cells). This type of cell replication is designed to increase the number of cells during the blastogenesis and embryogenesis of both animals and plants. The most distinct characteristic of the mitotic process is the production of two product cells (daughters) which are similar to each other as well as to their original cell (mother) in both quantitative and qualitative aspects
Binary fission has three types: simple, transverse, and longitudinal binary fission. Simple binary fission happens in amoebas wherein the division goes by any plane. Transverse binary fission happens among paramecium and planaria wherein the cytoplasmic division plane matches the specimen’s transverse axis. Longitudinal binary fission occurs in the euglena when the plane matches the longitudinal alignment.
A student makes the analogy that the cardiovascular system is like a highway. Why is this a good analogy? Blood is made of many different kinds of cells. The heart pumps blood through the veins. The heart is centralized in the body. Blood transports materials to and from different parts of the body.
Answer:
Explanation:
cardiovascular system is the circulatory system, it permits the circulation of blood and allows for transport of nutrients such as amino acids and electrolytes, oxygen and carbon dioxide gases, hormones, and blood cells in the body. It also helps the body to provide nourishment and fight against diseases and maintain homeostasis.
It is consider an high way because of its function. An high way allows for free passage, with often time no obstruction this is what cardiovascular system does they allow for movement of blood and essential nutrient in the body system for effective function of our body.
Answer:
D: Blood transports materials to and from different parts of the body.
