Answer:

If a pea plant has a recessive allele for green peas, it will produce... green pease if it does not also have a dominant allele for yellow peas. When Gregor Mendel crossed a tall plant with a short plant

Explanation:

Answer:

If a pea plant has a recessive allele for yellow pea , it will make an offspring yellow if it has a genotype yy.

Explanation:

The pea “color” gene comes in a yellow version (y), there are two possible combinations for this color gene: Yy and yy. In yy pea plants only make yellow peas because they only have the yellow version. If the new pea has a genotype Yy, it has other color because the yellow version, y, is recessive over the dominant version, Y.

Explanation:

Answer:Develop

Explanation:

Gene expression in the cells of multicellular organisms allows cells to grow, differentiate, and develop. So, it's D, i.e. all of the above.

Gene expression may be defined as the procedure by which the information encoded in a gene is utilized to either make RNA molecules that code for proteins or to construct non-coding RNA molecules that operate other functions.

Gene expression authorizes the cell to adapt to a specific condition and expresses different sets of genes that aid in maintaining the distinctive property of specific cells. This is known as differentiation.

Therefore, the correct option for this question is D.

Answer:

A

Explanation:

Isostatic equilibrium is used to state why some regions of the lithosphere have greater elevation than others. The crust ‘floats’on the‘liquid’ mantle below and different regions  of the crust submerge into the mantle differentially depending on their local densities or weight. Heavier regions such as in mountainous region (like the Himalayas) are sunken deeper into the mantle that other regions.  Every local region has its own local isostatic equilibrium.

Answer:

The correct option is Option C

i.e. Asthenosphere is denser than lithosphere.

Explanation:

Asthenosphere is the layer situated below the lithosphere.

Theory of isostasy says that the layers above the other layer must have lesser density. This has two explanations. Firstly, if its not hold, then the denser above layer would sink below the less denser bottom layer. Secondly, as we go inwards, the pressure increases. This leads to the lower layers have greater density. So, as Asthenosphere is situated below the lithosphere, it has higher density.

Carrying capacity

In logistic growth., growth rate decreases when population increases..bcoz population reaches carrying capacity (no. Of individuals environment can support).

Hope this helps you frnd

Answer:

Increase in population size, reaching carrying capacity and less number of resources.

Explanation:

The logistic growth curve is characterized by S- shaped curve, when the presence of resources becomes less and population size increases. This causes population size to reach to carrying capacity.

Thus, it causes Logistic growth curve in S- shape. For example- Yeast. The yeast is used in preparation of alcohols.

Answer:

The answer is A. Evaporation of water due to warmer temperature causes low thick clouds.

Explanation:

Evaporation is the process in which liquid is changed into gas due to increases temperature or pressure. It is an important part of water recycling in nature. water from sea, rivers and streams evaporate and form clouds which brings water back to earth by raining. Evaporation also causes cooling effect as during evaporation heat is absorbed from the environment. On the other hand the cloud formation and rain also induce cooling by bringing down the temperature.

both P waves and S waves can travell through solids.In advance, P waves can travel through gasses too but S waves can't.

Answer:

The correct answers are they shake the ground and they travel through solids.

Explanation:

When an earthquake occurs, waves are sent in various directions across the earth's surface.

These waves can be classified into two types: Body Waves and Surface Waves.

Within body waves we have two types: primary (P) and secondary (S).

Both travel through the interior of the earth from the place where the earthquake occurred, to several directions that are in the distance.

The P waves are the fastest and the first ones, and the S waves are the ones that come later.

Both waves shake the ground, being that only the P waves do it in the direction in which they are directed and the S waves do so perpendicularly or transversally.

Also, both waves can move through solid materials, but only P waves can move through liquid materials.

No they are not because they don’t contain chlorophyll which is the organelle that is in charge of the process.

Consumers cannot perform photosynthesis.

Explanation:

The food chain is composed of two main components namely producers and consumers. The plants are kept under producers as they are involved in the production of food through a process called photosynthesis required by the other living organism.

The food which is produced by the plant is used by itself as well as by all other living creatures. Animal are called consumers because they cannot prepare their own food and are dependent on plant or producers as they cannot perform photosynthesis.

Like words in a sentence, the DNA sequence of a gene determines the amino acid sequence for the protein it encodes.

A phase diagram assumes pressure is kept constant.

Answer: choice three

Answer:

pressure

Explanation:

The phase diagram is a graph used to indicate the temperature and pressure conditions necessary to obtain a substance in a specific physical state (solid, liquid or gas). In this type of diagram, pressure is a factor that is kept constant.

The x (horizontal) axis contains the temperature values, and the y (vertical) axis contains the pressure values. In addition, there are three curves connected to a single point (called a triple point), dividing the graph into three well-defined areas, as we can see in the diagram shown above.

In addition to indicating the conditions for the substance to be in a specific physical state, the phase diagram indicates the conditions for any change in physical state to occur.

There is a 50% chance they will have heterozygous round and a 50% chance they have homozygous Oval eyes

Spongebob has big round eyes(R) which is dominant over and oval eye shape(r) and he is heterozygous for his round eye shape and marries a sponge lady with oval shape eyes then the kids have a 50% chance to have big round eyes and a 50% chance to have oval eye shape.

If spongebob has big round eyes(R) which is dominant over and oval eye shape(r) and he is heterozygous for his round eye shape and marries a sponge lady with oval shape eyes then the outcome will be Heterozygous round = Rr, Oval = rr.

So all possible genetic outcomes are Rr, Rr, rr and rr. So the chances of a child with round eyes are 50% and the chances of a child with oval eyes are 50%.

Hence, Spongebob has big round eyes(R) which is dominant over and oval eye shape(r) and he is heterozygous for his round eye shape and marries a sponge lady with oval shape eyes then the kids have a 50% chance to have big round eyes and a 50% chance to have oval eye shape.

Elements and compounds

The two classes of pure substances are Elements and Compounds. An element is a pure substance made from a single type of atom and a compound is a pure substance made from two or more different elements that are chemically combined.

The two classes of pure substances are: Elements and Compounds. These are both characterized by having a uniform and definite composition that distinguishes them from mixtures.

Elements are pure substances that are made from a single type of atom. For example, the element Carbon consists entirely of carbon atoms. An element cannot be broken down into any other substance.

Compounds are pure substances that are made from two or more different elements that are chemically combined. For example, water is a compound made from hydrogen and oxygen. Compounds can be broken down into their component elements via chemical reactions.

Do you think it would be c

The correct answer is A. the absolute age of a fossil.

Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of decay of radioactive isotopes. This technique provides scientists with a highly accurate way to calculate the absolute age of a fossil by measuring the amount of radioactive decay that has occurred since the death of the organism.

Here's a brief explanation of why the other options are incorrect:

B. The transitional age of a fossil: Radiometric dating does not provide information about transitional ages, which refer to the evolutionary stages of organisms. It only gives the absolute age of the fossil.

C. The relative age of a fossil: Relative dating methods, such as stratigraphy, determine the relative order of past events by comparing the ages of geological strata. Radiometric dating, on the other hand, gives a numerical age and is therefore an absolute dating method.

D. The average age of a fossil: Radiometric dating provides a specific age for a fossil, not an average age. The age determined is the time since the organism died and was fossilized.

In summary, radiometric dating is a powerful tool in geochronology that allows for the direct determination of the absolute age of a fossil, which is why option A is the correct answer.
