Answer:
C
Explanation:
A totipotent cell can differentiate into any type of cell and is the potency with the highest differentiation potential. It is then followed by pluripotency, multipotency, then unipotency. The ability of a cell to have differentiation potential is governed by the ability of its silenced genes to be easily reactivated.
why does water of salt gets salty?
Answer:
Salt in the ocean comes from rocks on land. The rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water).

are consumers able to do photosynthesis ? why or why not ?
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.
if a pea plant has a recessive allele for yellow pea , it will
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.

what is residual waste ? a. waste that can be composted b. waste that can be recycled c. waste that can be recycled, but not composted d. waste that cannot be composted or recycled
Answer:
C, a waste that can be recycled, but not composted
Explanation:
waste that can be recycled, but not composted, residual waste is things leather, rubber, textiles, glass, industrial equipment, electronics, pumps, piping, storage tanks, filters, fertilizers, pesticides, pharmaceutical waste, detergents and cleaners, photographic film and paper, you can reporpose it but it will not compost
Answer:
d. waste that cannot be composted or recycled
Explanation:
The waste that is left once all the recyclable waste is removed is called residual waste. It includes the waste materials that can not be subjected to recycling or composting. These waste materials cannot be re-used.
Most of the residual waste is removed from the system by burying them in landfills. Some of the examples of residual wastes are CDs, DVDs, crayons, chewing gums, etc.
A phase diagram assumes ______ is kept constant.
temperature
volume
pressure
density
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.

What happens next after an mRNA strand separates from a DNA molecule?
Answer: DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.

Why does weather vary from day to day?
A. because weather is a complex interaction among many different variables that are constantly changing
B. because cold fronts are always followed by a series of colder fronts, before a warm front returns
C. because the Sun's energy heats all parts of the Earth evenly but does not heat the atmosphere
D. because the rotation of the Earth causes the atmosphere to expand and contract as it nears the Sun or Moon
Answer:
A
Explanation:
D is not correct because the atmosphere doesn't expand, C isn't correct because the Sun doesn't heat all the Earth evenly (hence different climates), B is not correct because cold fronts can be singular, so it has to be A

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.
What is Gene expression?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.

What can radiometric dating reveal
A.the absolute age of a fossil
B. The transitional age of a fossil
C. The relative age of a fossil
D. The average age of a fossil
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.

Which finding would have disproved Virchow’s hypothesis?
Animalcules are not organisms.
Animals are made of non–cell-based matter.
Plants are made of non–cell-based matter.
Cells can generate from nonliving matter.
Answer:
The correct answer will be option-Cells can generate from nonliving matter.
Explanation:
Rudolf Virchow is known for modifying the cell theory proposed by the Schleiden and Schwann in 1839. He added to the existed theory and suggested that all living cell come from the pre-existed cells.
But this hypothesis was disproved after the Miller and Urey performed an experiment in 1953 and demonstrated that cells were originated from the non-living matter present in the atmosphere during primordial time.
This fact disproved the hypothesis of Virchow ans thus is the correct answer.

Over millions of years of time, an island's vegetation shifts. The seed producing plants that
dominated the early origins of the island die out in favor of new species of plants that do
not produce seeds but provide a good habitat for insects. How is this change likely to
affect a species of birds that uses seeds as its primary source of lood and insects as a
secondary food source
A.The species will maintain its heritable traits while learning to make insects their
primary food source,
B.The species will decline and become endangered because its adaptations have
reduced utility
C.The species will split into two one adapted to eating seeds and a second
adapted to eating insects
D.over time a shift in trolts will be olvserved as the species adapts to an insect diet.
over time a shift in trolts will be olvserved as the species adapts to an insect diet
Final answer:
The species of birds that relied on seeds may decline due to the reduced utility of their adaptations, but if adaptable, trait shifts will occur towards an insect diet, potentially echoing Darwin's finches' adaptive radiation on the Galapagos Islands.
Explanation:
When an island's vegetation shifts and the seed-producing plants that previously dominated are replaced by non-seed-producing plants favorable to insects, the species of birds that primarily rely on seeds for food are likely to be affected in a specific way. Over time, if the birds cannot adapt to the available food sources, they may decline and become endangered due to the reduced utility of their seed-eating adaptations. However, if they have the flexibility to change their diet and learn to make insects their primary food source, then over time a shift in traits will be observed as the species adapts to the new food source through natural selection, potentially leading to an evolutionarily significant change in beak morphology or feeding behavior.

Which of these processes as a cooling affect on earth? (APEX)
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.
