A. Each of the cells in the organism will have its own nucleus.

Explanation:

While snorkeling in the ocean you find large, leafy organisms that are brownish in color growing in large masses. To be sure that they are protists since they look quite plant-like, the characteristic that the organism's cells exhibit will be that each of the cells in the organism will have its own nucleus.

This is because protists are eukaryotes, which simply means it has its own nucleus and are usually single celled.

Answer:

The Big Bang theory is the prevailing cosmological model explaining the existence of the observable universe from the earliest known periods through its subsequent large-scale evolution. The model describes how the universe expanded from an initial state of high density and temperature,and offers a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure.

Crucially, the theory is compatible with Hubble–Lemaître law—the observation that the farther away a galaxy is, the faster it is moving away from Earth. Extrapolating this cosmic expansion backwards in time using the known laws of physics, the theory describes an increasingly concentrated cosmos preceded by a singularity in which space and time lose meaning (typically named "the Big Bang singularity"). Detailed measurements of the expansion rate of the universe place the Big Bang singularity at around 13.8 billion years ago, which is thus considered the age of the universe.

After its initial expansion, an event that is by itself often called "the Big Bang", the universe cooled sufficiently to allow the formation of subatomic particles, and later atoms. Giant clouds of these primordial elements—mostly hydrogen, with some helium and lithium—later coalesced through gravity, forming early stars and galaxies, the descendants of which are visible today. Besides these primordial building materials, astronomers observe the gravitational effects of an unknown dark matter surrounding galaxies. Most of the gravitational potential in the universe seems to be in this form, and the Big Bang theory and various observations indicate that this excess gravitational potential is not created by baryonic matter, such as normal atoms. Measurements of the redshifts of supernovae indicate that the expansion of the universe is accelerating, an observation attributed to dark energy's existence.

Georges Lemaître first noted in 1927 that an expanding universe could be traced back in time to an originating single point, which he called the "primeval atom". Edwin Hubble confirmed through analysis of galactic redshifts in 1929 that galaxies are indeed drifting apart; this is important observational evidence for an expanding universe. For several decades, the scientific community was divided between supporters of the Big Bang and the rival steady-state model which both offered explanations for the observed expansion, but the steady-state model stipulated an eternal universe in contrast to the Big Bang's finite age. In 1964, the CMB was discovered, which convinced many cosmologists that the steady-state theory was falsified, since, unlike the steady-state theory, the hot Big Bang predicted a uniform background radiation throughout the universe caused by the high temperatures and densities in the distant past. A wide range of empirical evidence strongly favors the Big Bang, which is now essentially universally accepted.

Answer:

Females of reproductive age lose iron through menstrual blood

Explanation:

Iron is an essential micronutrient involved in the formation of hemoglobin, myoglobin and many enzymatic groups. Moreover, hemochromatosis is a genetically inherited disorder caused by mutations in genes associated with the processes of absorption, transport and storage of iron. The excess of iron is stored in different organs (e.g., liver, heart, pancreas, etc), causing characteristic tissue damage. During each menstrual cycle, women and girls suffer a blood loss of approximately 40 ml, which is associated with an average loss of 1.6 mg of iron. In consequence, it is expected that women of reproductive age (ie, 15–49 years) lose iron during their menstrual periods, thereby avoiding iron overload caused by hemochromatosis.

Answer:

159.01 mmHg

Explanation:

position of Heart = 2m  below the top of the head  given that the neck is fully extended

Determine the minimum diastolic pressure

Minimum diastolic Pressure = 1060 kg/m^3 * 10 m/s^2 * 2m

                                               = 21200 kg/m^2

convert the value to Pa

21200 kg/m^2 = 21200 Pa

( 1 pa = 0.00750062 mmHg )

Therefore : minimum diastolic pressure = 21200 * 0.00750062 = 159.01 mmHg

The minimum diastolic pressure that a giraffe must have is 150 mmHg

Diastolic Blood pressure is the pressure on the walls of your arteries between heartbeats, that is when the heart is resting.

P = hpg

where;

P = pressure

h = height difference

p = density

g = acceleration due to gravity

Density of blood = 1000 kg/m^3

h =2.0 m

g = 10 m/s^2

Pressure = 1000 × 2.0 × 10

Pressure = 20000 Pascal or 20 kpa

1 kpa = 7.50 mmHg

20 kpa = 20 × 7.50

Pressure = 150 mmHg

Therefore, the minimum diastolic pressure that a giraffe must have is 150 mmHg

Answer:

The valence electrons have a role in the bonding of two atoms. The nuclei of each atom are drawn together by their attraction to the valence electrons of the other atom. As the atoms are drawn together by their attractions, electrons from each atom are drawn to the nuclei of both atoms, where they are "shared."

Answer:

cells duplicate so when there is no cell it cant make any

Explanation:

The statement that there must be a preexisting cell in order for a new cell to form is known as cell theory.

The scientific idea that cells make up living organisms, that they are the fundamental structural and organizational unit of all species.

They all originate from previously existing cells is known as cell theory. It was first proposed in the middle of the nineteenth century.

Because cells are the building blocks of all life, cell theory is essential for our understanding of biology.

We can have single-celled organisms like yeasts and bacteria. All living things grow and develop on the basis of cell division, or the division of a cell from one to two to four.

A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.

Thus, the statement "cell arises from pre-existing cells" comes from cell theory.

Since the gene is located on the Y chromosome, and the Y chromosome is absent in females, the probability their first child will be a girl with hairy ears is zero

Explanation:

Y-linkage, also known as holandric inheritance is a form of sex linkage in which inherited traits in offsprings are produced by genes located on the Y chromosome. The Y chromosome is one of the sex-determining chromosomes and is present only in males. Males have a copy of the Y chromosome and an X chromosome while females have two copies of the X chromosome.

For a trait that is linked to the Ychromosome, the phenotypic effect occurs only in males and is always manifested in these males. Since the Y chromosome is absent in females, the character and its phenotypic effect are absent from daughters of trait carriers. Therefore, all daughters will be normal.

Since the gene for hair growth onnthe pinna is located on the Y chromosome, and the Y chromosome is absent in females, the probability their first child will be a girl with hairy ears is zero.

The probability that their first child will be a girl with hairy ears is zero.

The sex chromosomes in humans are the X and Y chromosomes. They determine the sex of a baby and also carry the sex linked traits. A baby girl results from XX  and a baby boy results from XY.

We are told that this gene for hairy ears is located on the Y chromosome. This chromosome is absent in a girl child. hence, the probability that their first child will be a girl with hairy ears is zero.
