Answer:
B. Blood in the left ventricle is deoxygenated.
Explanation:
Human heart consists of four chambers namely: right atrium, right ventricle, left atrium and left ventricle. These chambers work hand in hand to perform the function of circulating blood throughout the body.
- The RIGHT ATRIUM receives deoxygenated blood from the heart and passes it to the RIGHT VENTRICLE, which pumps it to the lungs in order to be oxygenated.
- The LEFT ATRIUM receives oxygenated blood from the lungs and passes it to the LEFT VENTRICLE, which pumps it into the body.
- Also, the pulmonary artery carries deoxygenated blood into the lungs for oxygenation while the pulmonary veins carry oxygenated blood from the lungs
Based on the above explanation of the right & left atria and the right & left ventricles, it is FALSE that the blood in the left ventricle is deoxygenated. It is rather oxygenated.

A scientist designed and conducted an experiment to test a hypothesis, and then formed a conclusion from her results. Next, she collected and analyzed more data and formed another conclusion. Which statement best justifies the fact that she skipped the hypothesis and experimental design steps of the scientific method?
Answer: The scientist was repeating the experiment to improve the validity of her data.
Explanation:
The scientific method involves the observation of natural phenomena and then the postulation of hypotheses and their testing by experimentation. The knowledge we have represents scientific hypotheses and theories supported by observations and experiments (empirical method).
Experiments are performed to support/validate or refute one or many hypothesis. Several experiments provide insight into cause-and-effect by demonstrating what result occurs when a particular factor is manipulated.
A scientific hypothesis is an acceptable proposition that has been formulated through the collection of information and data, although unconfirmed, serves to provide an alternative answer to a scientifically based problem. Also when a research work is carried out, a conclusion should be drawn, which in these cases is an argument or statement that synthesizes the work done. The main ideas are taken and the research is summarized, explaining in the author's own words the reason for the results obtained. In the case of a discussion, the personal point of view of each of the members that participated in the experiment are exposed.
Since the scientist repeated the previous experiment to improve the validity of her data, that justifies the fact that she skipped the hypothesis and experiment. With the first results of the experiment, I formulate a conclusion. Then, with other results of the same experiment, he formulated another conclusion. So there is no need to repeat the experiment, because it is the same.

The picture below shows the satellite image of ocean surfaces on Earth at Locations A, B, C, and D.
Which of these graphs best models the waves in the four locations?
When using images and graphs to express the results of a research, both of them should express the same information to make their interpretation easier. Option A is the one that best models the waves in the four locations.
How to express the results of a research?
There are different ways in which a researcher can correctly express the results of an experiment or research. It can be done by using images, tables, graphs, diagrams, etcetera.
Usually, combinations of one or more are used to express the same results in order to make it easier to make interpretations (for instance, tables and charts). In these cases, the same data must be expressed in all of them, so the interpretation is coherent.
In any case, there must always be a reference to what is being shown, so the persons looking at the image, chart, or table, get to know what they are looking at.
For instance, in the exposed example we can see the satellite image of ocean surfaces on Earth at different locations.
To get to understand this image by itself, we need references. These are given below in the sea surface height anomaly gradient.
This gradient explains the change in height from the lowest height -the darkest color that reflects -50 cm-, to the highest height -white expresses 50 cm-.
Letters A, B, C, and D are references to the locations that were considered.
If we want to make a graph with this same information, we need to make a good interpretation of the image and then reflect it in the graph.
In the exposed example, graph A is the one that best reflects the information provided in the image but is not entirely correct.
Image
A ⇒ red color ⇒ 30 cmB ⇒ yellow color ⇒ 10 cm C ⇒ cream/light blue ⇒ 0 cmD ⇒ light blue color ⇒ -10 cm
The graph must express the change in water surface height. This change is expressed in the Y ax of the chart.
Probably the X ax represents normal heights.
According to the information,
A and B must be over the X ax (positive values). C might be on the ax or slightly over or below it. Finally, D must be below the X ax (negative value).
Graph A is the one that best represents this information.

Explanation:
similarities between the vas deferens of a male reproductive system and fallopian tube of a female reproductive system are ?
Answer:
Vas deferens → Male reproductive system
Fallopian tube → Female reproductive system.
Explanation:
In vertebrates, there are paired gonoducts for the movement of gametes from the gonads. Humans are no different.
1. Vas deferens is a male gonoduct that transports sperm away from the testes in preparation for ejaculation. Vas deferens collects secretion from seminal vesicle and becomes ejaculatory duct before draining in male urethra.
2. The fallopian tube is a female gonoduct that receives ova from the ovary when ovulation occurs. Fertilization occurs in the fallopian tube, and the early embryo moves from the tube to the uterine cavity.
3. Ciliated pseudostratified epithelium lines the vas deferens, while ciliated columnar epithelium lines the fallopian tube.

Create a mutant fly with any number of variations and mate it with a
wild-type fly. How many offspring are wild-type? What are the
phenotypes of the flies that are not wild-type?
Untamed type, a person who exhibits the typical phenotype, which is the phenotype typically present in a population of living things. Mutant, a person who deviates from the typical phenotype in some way.
What are the phenotypes of the flies that are not wild-type?The phenotypic of a species' normal form as it appears in nature is known as the wild type (WT). The wild type was initially thought to result from the “regular” standard allele at a location, as opposed to a non-standard, “mutant” allele.
Type wild, an individual with the typical phenotype, or the phenotype typically present in a population of living things in the wild. Mutant, a person, has a phenotype that is different from the typical phenotype.

If the half-life of a radioactive atom is 3,500 years. How old is the substance if the parent-daughter ratio is 1:127?
Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
Half-life of the radioactive atom (t1/2): 3,500 yearsParent-daughter ratio ([A]/[A]₀): 1:127 (1/127)Step 2: Calculate the rate constant
Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.
k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹
Step 3: Calculate the time elapsed (t)
For first-order kinetics, we will use the following expression.
ln ([A]/[A]₀) = -k × t
t = ln ([A]/[A]₀)/ (-k)
t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y

Explanation:
The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants. To protect itself against the ants, it ejects fibers from a tuft located at the tail end of its body. The tufts have hooks at the tips and barbs along their length that lock and interlink with the ant’s setae, small hairs that cover the body of the ant. When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it. As the ant attempts to remove the tufts, it entangles itself more, becoming immobilized.Which two systems most directly interact in the fuzzy millipede’s defense against ants?
