Answer: C) Gg

Explanation:

A heterozygous mixtures include two different genes:

A Dominant and a Reccessive gene. Inorder to have a mixture, you need two different genes, explaining why it would be C.

Determining the genomes of each species to see which is similar will provide the best evidence regarding the evolutionary relationship of these species. So the correct option is B.

The relationships of different species with each other based on their history of evolution are called evolutionary relationships.

The study of the relationships between organisms by categorizing them into various kinds of groups is called systematics.

All the species of organisms, from bacteria to mammals have evolved from some kind of ancestral species by the process of evolution.

Determination of these evolutionary relationships is the key to understanding the process of evolution. Evolutionary relationships are determined by using evolutionary trees which are diagrammatic representations of ancestral species and their descendants.

The study of genomics to identify the similarity between organisms is yet another useful tool to determine the relationship between them.

Therefore the correct option is B.

Explanation:

Answer:

I think the answer is B. I think energy decreases as it moves up tropic levels when it is lost as the organisms from one level consume the organisms in the other.

Explanation:

It can't be A because animals do travel from one ecosystem to another. It's migration. It's not C because air can be used by organisms as once as the air moves out of their ecosystem because air is everywhere and the organisms need air to breathe and to live. D is definitely incorrect because matter can't be created or destroyed. Remember that an ecosystem is the organisms physical environment. I hope this answers your question.

D, matter lost by one ecosystem is gained by the surrounding environment

Explanation: Here's an explanation for why D is right and all the other ones are wrong.
D- when matter is lost from one ecosystem, it is often gained by another nearby ecosystem. For example, when leaves fall from trees in a forest, they decompose and release nutrients into the soil. These nutrients can then be taken up by plants in the same ecosystem or be transported by water runoff to other ecosystems, such as rivers or lakes. This process of matter transfer ensures the cycling of nutrients within and between ecosystems.
A- animals can and do travel from one ecosystem to another. Birds migrate between different habitats, and some animals spread seeds or pollinate flowers in multiple ecosystems. B- the total amount of energy in an ecosystem does change over time. Energy enters an ecosystem through photosynthesis, where plants convert sunlight into chemical energy. This energy is then passed on to other organisms through the food chain. However, energy is lost as heat during these transfers and eventually leaves the ecosystem, resulting in a decrease in the total amount of energy available. C- organisms rely on air for respiration, and the exchange of gases, like oxygen and carbon dioxide, occue between organisms and the air in the environment. While air moves in and out of ecosystems, organisms continuously utilize the air for their survival.

Answer:

The correct answer is - A. through the use of earthquake waves.

Explanation:

The interior of the earth can not be studied or seen by digging the hole, for that scientist normally use the movement of seismic waves, from earthquakes or nuclear test explosions, are reflected, slow down, sped up bent by passing through the different layers.

Waves behave differently as they move in different layers and their material helps scientists to learn and study the layers and their constituents. It explains that the Earth's interior has a series of concentric shells, with a thin outer crust, a mantle, a liquid outer core, and a solid inner core.

Answer:

In speciation, organisms evolved with the passage of time.

Explanation:

Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one.  Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

Answer: A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a GENE.

Explanation:

CHROMOSOMES are made up of two threads called chromatids joined at a point called the centromere.

In the chemical nature of chromosomes, each is made up of a protein framework which has a long molecule of DNA (deoxyribonucleic acid) coiled round it. A segment of DNA containing the instructions for building a protein which will result in a trait is called a GENE.

The GENES in the cell of a diploid organism contain all the necessary instructions for building up the organism.These instructions are written on a molecular scale.. Most genes contain information to direct the synthesis of specific proteins. Each such protein takes part in the development of a particular character.

A protein is made up of one or more chains of amino acids known as polypeptides. The sequence of bases in a DNA molecule determines the type of amino acid and the sequence in which they are arranged in a polypeptide chain.

A gene therefore is a sequence of triplets of the four bases which specifies the structure of a protein

Answer:

[tex]0.05\times 10^{-3}\ \text{m}^3[/tex]

[tex]800\ \text{kg/m}^3[/tex]

Explanation:

[tex]W_b[/tex] = Weight of bottle = 0.25 N

[tex]W_w[/tex] = Weight of water = [tex]0.75-0.25=0.5\ \text{N}[/tex]

g = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]

[tex]\rho_w[/tex] = Density of water = [tex]1000\ \text{kg/m}^3[/tex]

Mass of water

[tex]m_w=\dfrac{W_w}{g}\\\Rightarrow m_w=\dfrac{0.5}{10}\\\Rightarrow m_w=0.05\ \text{kg}[/tex]

Volume is given by

[tex]V_w=\dfrac{m_w}{\rho_w}\\\Rightarrow V_w=\dfrac{0.05}{1000}\\\Rightarrow V_w=0.05\times 10^{-3}\ \text{m}^3[/tex]

Volume of the bottle is [tex]0.05\times 10^{-3}\ \text{m}^3[/tex].

This means that the alcohol will take the same amount of volume.

[tex]W_a[/tex] = Weight of alcohol = [tex]0.65-0.25=0.4\ \text{N}[/tex]

Mass of alcohol

[tex]m_a=\dfrac{0.4}{10}\\\Rightarrow m_a=0.04\ \text{kg}[/tex]

Density is given by

[tex]\rho=\dfrac{m_a}{V_w}\\\Rightarrow \rho=\dfrac{0.04}{0.05\times 10^{-3}}\\\Rightarrow \rho=800\ \text{kg/m}^3[/tex]

Density of alcohol is [tex]800\ \text{kg/m}^3[/tex]

The volume of the bottle is 50 mL and the density of alcohol is 0.8 g/c[tex]m^{3}[/tex]

The weight of empty bottle is 0.25N

the weight of bottle filled with water is 0.75N

therefore, the weight of water in the bottle is 0.75N - 0.25N = 0.50N

we know that weight,  w =mg , where m is the mass of substance and g is acceleration due to gravity. Here we will take g= 10 m/[tex]s^{2}[/tex] for simplicity.

⇒       m =  w/g = 0.5/10 = 0.05 kg

⇒ mass of water is 50g

now, the density of water ρ(w) = 1g/[tex]cm^{3}[/tex] = 1g/mL

relation between mass, density and volume is:

                     V = m/ρ = 50/1 = 50mL

Hence the volume of the bottle is 50mL.

Now it is given that the weight of bottle filled with alcohol is 0.65N

⇒ weight of alcohol = 0.40N

⇒ mass of alcohol = 0.40/g = 0.40/10 = 0.040kg = 40g

The volume of the bottle remains the same, so to calculate the density of alcohol we use the above mentioned relation between mass, density, and volume on alcohol.

That is,   V = m/ρ

            ⇒ ρ(al) = m/V = 40/50 g/c[tex]m^{3}[/tex]

                ρ(al) = 0.8 g/c[tex]m^{3}[/tex] or 0.8 g/mL

Explanation:

The knob of a door always has a larger radius than the shaft so that the distance over which the force is applied increases in order to decrease the effort force needed to open the door. Thus, the correct option for this question is D.

A force may be defined as an instance of pushing or pulling on an object with mass. This causes an object to change its velocity. It is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction, so it is a vector quantity.

According to the context of this question, a door knob is an example of a wheel and axle. The force that is applied on the knob of the door may effectively increase when it is operated by a person. This stimulates a reduction in the effort through which force is needed to open the door.

Therefore, the correct option for this question is D.
