Answer: Yes
Explanation:
Our Solar System is an orderly place, with the four inner planets, the asteroid belt, and the gas giant worlds all orbiting in the same plane around the Sun. Even as you go farther out, the Kuiper belt objects appear to line up with that same exact plane. Given that the Sun is spherical and that there are stars appearing with planets orbiting in every direction imaginable, it seems too much of a coincidence to be random chance that all these worlds line up. In fact, practically every Solar System we've observed outside of our own appears to have their worlds line up in the same plane, too, wherever we've been able to detect it.

Which is a characteristic of nuclear fusion?
A: produces radioactive waste
B: involves the collision of two nuclei
C: commonly used by humans as an energy source
D: requires very little activation energy
Answer:
B.Involves the collision of two nuclei energy source
Explanation:
A characteristic of nuclear fusion is that it involves the collision of two nuclei.
What is nuclear fusion ?
Nuclear fusion is a reaction through which two or more light nuclei collide to form a heavier nucleus.
The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

Which method of classification requires that each taxonomic group be monophyletic
Answer:
Cladistics
Explanation:
Cladistics is the most scientific method used to classify organisms that are categorized into distinct groups or 'clades'. The cladistic approach is derived from the studies made by the entomologist Emil Hans Willi Hennig (1913-1976). This methodology is based on the identification of the most recent common ancestor (MCRA), where organisms are classified based on shared traits (i.e., how similar they are). By using this method it is possible to draw a cladogram, i.e, an evolutionary tree that exhibits the ancestral relationships among organisms.

Which can be accomplished by an interrupted mating experiment between Hfr and F- bacteria? Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome. Interrupted mating experiments can determine the physical distance between genes on the F- bacterial chromosome. Interrupted mating experiments can determine the genome size of the Hfr bacteria. Interrupted mating experiments can determine the DNA sequence of the Hfr bacterial chromosome. Interrupted mating experiments can determine the gene order on the F- bacterial chromosome.
Answer:
Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome.
Explanation:
Interrupted mating is a technique used in experiments involving microbiology. This experiment was created by geneticists François Jacob and Elie Wollman, in the late 1950s. This technique allows the mapping of the genes of the bacteria involved in the place where the conjugation was interrupted, within monitored and controlled time intervals. In this way, the technique allows showing the transfer mechanisms and the gene transfer itself.
In relation to the question above, we can say that the interrupted mating experiments can determine the order of the genes on the bacterial chromosome Hfr.

O All chemical reactions become slower, because low pH makes reactions occur slower.
O Cells keep functioning normally because cells are not affected by pH changes.
Answer: B) Enzymes may lose their ability to carry out reactions because their shape changes.
Explanation:
The shapes of Enzymes may change when the PH level changes.
You are doing an experiment involving antibiotic resistance in your study bacteria. This organism grows well on LB - Miller agar plates. You want to make 50 plates (assuming 25ml/plate) of LB-Miller at 1.5% agar concentration. Twenty-five of these plates will be plain, the other 25 need to contain 50 micrograms/ml of Gentamycin for your resistance experiments. You have a stock solution of Gentamycin at a concentration of 5 mg/ml. How would you go about making your plates
Answer:
See the answer below
Explanation:
The stock solution of Gentamycin has a concentration of 5 mg/ml while each plate needs to contain 50 micrograms/ml of Gentamycin.
5 mg/ml = 5000 micrograms/ml
There is a need to dilute the stock antibiotic solution in order to arrive at 50 micrograms/ml. Using the dilution principle;
m1v1 = m2v2
5000 x 1 = 50 x v2
v2 = 5000/50 = 1000 ml
Hence, in order to prepare 50 micrograms/ml, 1 ml of the stock Gentamycin should be taken and diluted with 999 ml of distilled sterilized water. 1 ml of the diluted Gentamycin will then be added to each agar plate while they are still in the molten form at a warm temperature.
Indicate whether each statement is true or false. 1. Intramembranous ossification is completed by birth. (Click to select) 2. Within the spongy bone that is formed by intramembranous ossification, there are spaces that contain developing red bone marrow. (Click to select) 3. The end products of intramembranous bone formation are bones with outer compact bone surfaces and spongy centers. (Click to select)
Answer:
1. False
2. True
3. True
Explanation:
Intramembranous ossification is a process by which flat bones are formed. This mechanism involves the development of the bones on the top of the skull. Intramembranous bones are developed by the differentiation of the mesenchyme cells into osteogenic cells which in turn become osteoblasts. Intramembranous ossification formation is completed by the end of the adolescent growth spurt. The spongy bone is a highly porous structure localized inside the bones which is lighter than compact bone, while bone marrow is a soft connective tissue localized within the spongy portions of bones.

is liquid water more dense than ice
Answer:
Yes, liquid water is more dense than ice.
Explanation:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Which condition is autosomal recessive?
a) neurofibromatosis type 1
b) hemophilia
c) sickle cell anemia
d) Rett syndrome
Answer:
c, sickle cell anemia
Explanation:
When you are conceived you (generally) receive one set of chromosomes from your mom and one from your dad. Recessive diseases mean that you must receive 2 copies of the mutated gene (disease gene) to express the disease (one from mom and one from dad). Dominant means that you only need one copy of the mutated gene to express the disease.
Sickle cell anemia is a disease caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. The mutation is on an autosome (not a sex chromosome). You need two copies of the bad gene in order to express it.

The spine normally has several gentle curves when viewed from the side. These curves of the spine work in harmony to keep the body’s center of gravity aligned over the pelvis. The cervical spine has a gentle lordosis (inward curve). The thoracic spine has a gentle kyphosis (outward curve). And the lumbar spine has a gentle lordosis (inward curve) again. Discuss deformities of the spine curvature, types and how they affect the body position. Define some of the surgical procedures that can correct these deficites.
A) Discuss deformities of the spine curvature, types and how they affect the body position.
A normal spine when viewed from the back should run straight down the middle of the back.
Deviation from the normal,when an abnormality of the spine sets in, this natural curvature of the spine gets misaligned or exaggerated in some areas.
There are three (3) main types of spine curvature disorders/deformities which are;
LORDOSIS; Lordosis is also known as Swayback, when someone presents with Lordosis,the spine of the Individual curves/sways significantly inward at the lower back.
Lordosis affects posture through the following ways;
-Appearance of swayback, and the buttocks being/appearing more pronounced.
-Problem with moving certain ways.
- There is a large gap between the person's lower back and the floor when the person lies down on the back especially on a hard surface and this does not change when the person bends forward.
KYPHOSIS; KYPHOSIS yet another spine curvature deformity is characterised by a spine that assumed an abnormally rounded upper back.( This curvature is more then 50 degrees). KYPHOSIS affects posture through the following ways;
-There is obvious bending forward of the head compared to the rest of the body.
-There is also a hump or curve to the upper back of the Individual.
SCOLIOSIS; In Scoliosis, another deformity of the spine curvature.
The Individual that presents with scoliosis have a curve that is sideways and goes to their spine. In scoliosis,the curve is often C shaped or S shaped.
In Scoliosis,there are;
- An uneven shoulder blades with one being higher than the other.
- There is also an uneven waist or hip.
- The Individual leans toward one side.
B) Define some of the surgical procedures that can correct these deficites.
SPINE INSTRUMENTATIONS; This involves using instruments like rods,wire and hooks to attach to the spine inorder to realign the bones of the spine and keep the bones secure.This surgery often follows a spinal fusion.
ARTIFICIAL DISC REPLACEMENT; This is when degenerated discs of the spine are surgically replaced with artificial discs.
KYPHOPLASTY; This involves surgically inserting or placing a balloon inside the affected spine area inorder to stabilize and strengthen it and also to relieve pain.
