A person has three liters of extracellular water in blood (vascular volume). Assuming 70% of the body weight is from water. Calculate the weight of this person.

The true statement about human samples from a body is hair samples can be different even when taken from the same person. The correct option is d.

A hair sample is often obtained from a person's head and consists of a collection of hair strands. Hair from the previous year is commonly found in hair samples.

Despite the fact that hair growth varies, an average of 5 inches of hair is added in 12 months. These characteristics, as well as hair's resistance to water and stretching, all have an impact on how it looks on a regular basis.

Therefore, the correct option is d, Hair samples can be different even when taken from the same person.

Explanation:

Fungi doesn't use photosynthesis and isn't a prokaryotic heterotrophs and letter B is also wrong which leaves letter D.

Hope i helped, good luck on the test :)

The statement which is true about Fungi are as follows:

Thus, the correct option is D.

Fungi may be defined as a group of eukaryotic organisms that lack chlorophyll, leaves, true stems, and roots, reproduce by spores and live as saprotrophs or parasites.

Due to the absence of chloroplasts, fungi are not similar to plants. Fungi are eukaryotic heterotrophs organisms.

Spores are the fundamental reproductive units of fungi. The reproductive organs of a fungus are the Mycelium which is hidden until it is able to develop one or more fruiting bodies.

Therefore, the correct option for this question is D.

The energy is related to the change of state represented by the model by: D. Atoms lose energy as a gas changes to a liquid.

A model of the transition from a gas to a liquid is shown in the accompanying image. It demonstrates how atoms or molecules change from being widely scattered as in a gas to being concentrated as in a liquid.

The atoms in this process move from a higher-energy state  to a lower-energy state releasing or losing energy in the process. The most common kind of energy loss is heat.

Answer: A

Explanation:

It has the highest temperature + brightness

OD. It allows scientists to interpret data visually.

The main reason for displaying data in a graph is to make the data more interpretable, accessible and easy to understand. Graphs allow scientists to visually represent the data and identify patterns, trends, and relationships that may be difficult to discern from the raw data or from a table. By displaying data in a graph, scientists can quickly and easily identify outliers, compare different data sets, and make predictions. Additionally, graphs are a powerful tool for communicating research findings to others, as they can be easily understood and interpreted by a wide audience, including scientists, policymakers, and the general public.

OA. It helps scientists identify errors in an experiment's design.

OB. It shows more data than a table does.

C. It proves the scientific validity of the hypothesis.

All these options can be useful too, but they are not the main reason for displaying data in a graph.

Answer:

D

Explanation:

A and B are wrong since the whole point of unzipping a DNA molecule is to separate the paired bases so replication can occur off of each template strand. C is incorrect since there are no amino acids in DNA strands. D would be the answer as that is just what the structure of DNA looks like

Bacteria, Archaea, and Eukarya are the three domains of the global phylogenetic tree.

Population growth rate for Zambia is 0.8 % when CBR= 2.9%, Immigration = 1%,CDR = 2.1%, Emigration = 1% are as given above.

The crude birth rate is the number of live births per 1,000 of the population at the midyear census. long explanation The crude birth rate is the number of live births per 1,000 of the expected population at the midyear mark.

Given data;

CBR= 2.9%, Immigration = 1%,

CDR = 2.1%, Emigration = 1%

Now to find the Population Growth Rate use the given formula;

(CBR + Immigration) - (CDR + Emigration) = Population Growth Rate

Population Growth Rate= (CBR + Immigration) - (CDR + Emigration)

the current population of Zambia =18.92 million

now

CBR= 2.9% of 18.92 million=548680

CDR = 2.1% of 18.92 million=397320

Immigration = 1% of 18.92 million=189200

Emigration = 1% of 18.92 million=189200

now putting the values on eq.

Population Growth Rate= (CBR + Immigration) - (CDR + Emigration)

Population Growth Rate= (548680  +189200)-(397320 + 189200 )

Population Growth Rate=151360 *100/18.92 million

Population Growth Rate=0.8%

The balloons repelled each other because they both are electrically charged.

electrically charged object produces electrostatic force . Two electrically charged object repels each other . So both balloons are charged

The balloons repelled from each other because they both are electrically charged and as we know electrically charged object produces electrostatic force, they repels each other .

The electrostatic force attraction or repulsion is defined as the force exists between two charged particles which is also known as Coulomb’s interaction or force, the atom's stability can be maintained by  the electrostatic force between protons and electrons.

For example,  a balloon is rubbed with human hairs and come close to another balloon, so they stick together, Lightning  due to electrostatic force, ironing a silk ,  it clings to the body due to electrostatic force.

Answer:

A bacterium would be the best choice in this case

Explanation:

Bacteria are small, single-celled organisms which reproduce quickly and easily; it is made of only one cell, it reproduces every 20 minutes, it does not make people sick, it cannot survive outside the lab, etc.

Among the options given, the best choice for a genetic transformation is implemented for a bacterium. Thus, the correct option for this question is A.

Transformation may be defined as a process of horizontal gene transfer through which some bacteria take up foreign genetic material (unaided DNA) from the environment. This technique was first reported in Streptococcus pneumoniae by Griffith in 1928.

The population of bacteria utilizes three techniques in order to reproduce and permits genetic variations. They are conjugation, transformation, and transduction. Bacteria are small, single-celled organisms that reproduce quickly and easily in nature.

Transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from a surrounding atmosphere.

Therefore, the best choice for a genetic transformation is implemented for a bacterium. Thus, the correct option for this question is A.

a) An example of a behavioral event in animals that occurs in response to a 24-hour light/dark cycle is the circadian rhythm.

Circadian rhythms are internal biological processes that repeat approximately every 24 hours and are synchronized with the light/dark cycle of a day.

These rhythms regulate various physiological and behavioral processes in animals, including sleep-wake cycles, hormone secretion, body temperature, and activity levels.

b) An example of a behavioral event in plants that occurs in response to a seasonal cycle is flowering.

Many plant species exhibit a phenomenon called photoperiodism, where their flowering is influenced by the duration of daylight and darkness in a day.

This response allows plants to time their reproductive phase to favorable seasons for pollination, resource availability, and seed production.

Thus, these examples illustrate how different mechanisms in animals and plants regulate behaviors in response to specific environmental cycles.
