Final answer:
A person with a sex-linked inheritable disease has the gene present on the X chromosome. Females who carry the disease gene are carriers and do not show symptoms, while males will always show symptoms if they have the disease gene on their X chromosome. So, the correct statement is "The gene is always present on an X chromosome".
Explanation:
A person with a sex-linked inheritable disease would have the gene present on the X chromosome. The X chromosome is one of the two sex chromosomes, and females have two X chromosomes while males have one X and one Y chromosome. Females who carry the disease gene on one of their X chromosomes are carriers and do not show symptoms of the disease, while males will always have the disease if their X chromosome carries the disease gene.

What are the genotypes
Genotype is all the information / genetic material of an individual.
the genotype is constituted by the set of hereditary characteristics specific to an individual and the phenotype corresponds to the expression of this genetic inheritance in a given environment. It reports on the anatomical and physiological characteristics of an individual. The existence of dominant and recessive genes explains that the same phenotype corresponds to different genotypes.
Phenotype is your physical characteristic as Brown for the color of your eyes or blond for the color of your hair
While Genotype is the combination of genes that you have (basically your two parents give you a genes for a characteristic and that's the scientific expression) so B = a hairy brown and b = a blond so you can have BB = you're brown Bb = you're brown or bb = you're blond
So for example your phenotype is to be brown and your genotype is either Bb or BB
a. Heterozygous free earlobes
b. Homozygous dimples
c. Heterozygous dimples

The following events occur during sexual reproduction: A-mitosis B- meiosis C-fertilization D-birth. Which sequence represents the correct order of these events during sexual reproduciton? *
The correct order of events occurring in sexual reproduction is:
1. Meiosis
2. Fertilization
3. Mitosis
4. Birth
Explanation:
The type of reproduction in which fission of male and female gametes leads to the formation of embryo is called sexual reproduction. The first step in this process is gametogenesis in which through meiosis mode of cell division, male and female gametes formed.
Secondly the so formed gametes fuses with one another in the process called as fertilization. As a result of fertilization embryo forms. Through mitosis mode of cell division, the embryo gets converted into zygote after which birth occurs.

Which of the following is a necessary trait of a good hypothesis?
A.
It includes a reference to the theory from which the hypothesis was derived.
B.
It is written in the form of a question.
C.
It is clear and testable.
Correct Answer: C.
A hypothesis must have a clear prediction along with a rationale for that prediction. This can written in the "If...then...because..." format. For instance, a good hypothesis could be "if the temperature rises above 100°C then the water will boil because water's boiling point is 100°C.
The whole point of the experiment then is to test the hypothesis. By the end of the experiment there will either be supportive evidence for the hypothesis or a lack thereof. Either way, it was a testable hypothesis.
A necessary trait of a good hypothesis is that it is clear and testable.
Explanation:A necessary trait of a good hypothesis is that it is clear and testable. The hypothesis should be formulated in a way that allows it to be tested and either supported or refuted through observation or experimentation. It should be specific and measurable, so that data can be collected and analyzed to determine its validity.

Which sentence best describes these two cell models? Apex (Sentences located in image)
Answer:the answer is, “They have the same volume, but model B has more surface area.”
Explanation:
The sentence which best describes these two cell models is: C. They have the same volume, but model B has more surface area.
A cell can be defined as the fundamental (basic) functional, structural and smallest unit of life, which is mainly found in all living organisms.
The size of a living cell is limited by the following:
The rate at which materials move across the cell's membrane.The efficiency of the cell in using its DNA information.The ratio of surface area to volume.In this scenario, we can deduce from the diagram that both cell model A and cell model B have the same volume.
However, cell model B has more surface area than cell model A because the particles within it spread across faster.

What happens to energy when ADP AND P come together to make ATP?
Answer:
Energy is absorbed
Explanation:
The phosphate bonds of ATP are high energy bonds. One phosphate bond can have an energy of ΔG of -30.5 kJ/mol. This is why ATP is an ideal energy molecule for cells because they preserve the energy of cellular respiration, derived from energy molecules, into their bonds. Later the energy can be harnessed when the ATP is hydrolyzed in a biochemical reaction.
ATP+H2O→ADP+Pi ΔG = -30.5 kJ/mol
ATP+H2O→AMP+2Pi ΔG = -61 kJ/mol
2ADP+H2O→2AMP+2Pi ΔG = -61 kJ/mol

A. straightening the wire, because the number of turns of the wire around the iron core is directly proportional with the strength of electromagnet.
and,
C. decreasing the voltage is correct, by decreasing the voltage, the current will decrease and this leads to weaker electromagnet.
Explanation:
Simply, the electromagnet is used to convert electric energy to magnetic energy.
Basic idea:
The basic idea of the electromagnet is, when the electric current passes through a wire it creates a weak magnetic fieldComponents of simple electromagnet:

The strength of an electromagnet can be decreased by straightening the wire and reducing the voltage. Both of these methods reduce the magnetic field generated and thus decrease the power of the electromagnet.
Explanation:The strength of an electromagnet can be decreased in several ways, according to the options provided. One option is by straightening the wire (option a). In electromagnets, a coiled wire is often used to create a stronger magnetic field. Straightening the wire thus reduces the number of coils and decreases the magnetic field strength. Another option is by decreasing the voltage (option c). The strength of an electromagnet is directly proportional to the current that goes through the wire. As voltage drives this current, decreasing the voltage will indeed decrease the power of the electromagnet. The other options, increasing the current, decreasing the resistance, and increasing the number of wire loops, would all serve to increase the strength of the electromagnet, rather than decrease it.

-~- WolfieWolfFromSketch -~-Answer:
Option (2)
Explanation:
The lithosphere is the region that is comprised of the crust and a portion of the upper mantle. It is a region where all the essential minerals are present and also the living beings exist. It is made of rocks of variable composition. The lithosphere is made up of numerous large and small plates that are constantly in motion over the less dense asthenosphere layer, due to the convection current that generates in the mantle. This convection current initiates because of the heat radiated from the core of the earth.
Thus, this movement of the lithosphere is known as the plate tectonic movement.
Hence, the most appropriate answer is option (2).
What are some examples of evidence that support Wegener’s hypothesis of continental drift ?
Continental drift was a theory that explained how continents shift position on Earth's surface.
Wegener believed that all the continents were once joined together in an "Urkontinent" before breaking up and drifting to their current positions. Many scientists disbelieved his theory, however, it did introduce the idea of moving continents to geoscience. Hence, it was determined decades later, due to his findings of rocks and fossils that spread throughout the continents, the past existence of a supercontinent had at one point joined all the world's landmasses as one. Pangaea was a supercontinent that formed roughly 200 to 250 million years ago, according to the U.S. Geological Survey (USGS) and was responsible for the fossil and rock clues that led Wegener to his theory.
Wegener knew that fossil plants and animals such as mesosaurs, a freshwater reptiles that were found only South America and Africa during the Permian period, could be found on many continents. He also matched up rocks on either side of the Atlantic Ocean like puzzle pieces. For example, the Appalachian Mountains (United States) and Caledonian Mountains (Scotland) fit together, as do the Karroo strata in South Africa and Santa Catarina rocks in Brazil.
Wegener's hypothesis of continental drift is supported by fossil evidence.
What is continental drift theory?According to the Theory of Continental Drift, the continents of the Earth move relative to one another and appear to be drifting over the ocean floor together.
During one or more geologic periods, continents moved horizontally at a huge scale in relation to one another and to the ocean basins. The theory of plate tectonics, which integrates this idea, had this idea as a key antecedent.
The fossil record is one sort of evidence that has been used to support the Theory of Continental Drift. In rocks of similar age, scientists have discovered fossils of related plant and animal species. The coastlines of many continents were home to these rocks.

Sexual reproduction in a species usually results in
Higher genetic diversity.
Random mutations
Evolution.
Anything specific?
Sexual reproduction in a species usually results in genetic variation.
How does this sexual reproduction lead to this?This is because the two parents that contribute to the offspring share only some of their genes. The offspring will therefore have a unique combination of genes that is different from either parent.
Genetic variation is important for a species because it allows the species to adapt to changes in the environment. If the environment changes, some individuals in the species may have genes that allow them to survive and reproduce in the new environment. These individuals will pass on their genes to their offspring, and the species will gradually adapt to the new environment.

Chemical an mechanical these two are the main ways to make energy
Wind farms are mechanical and bio-conversion is chemical
Answer:
Option B, Mechanical energy
Explanation:
In the electricity production, whatsoever be the medium/raw material used for electricity production, the ultimate goal is to rotate the turbine of the generator which is connected to a coil held between two magnets. This is so because until unless the coil rotate between the magnets no electricity will be produced. Since rotation of a coil is linked to rotation of turbine which is nothing but a kind of mechanical exercise. Thus, it can be said that the generation of electricity relies primarily on mechanical energy.
