A black hybrid rabbit is crossed with a white purebred rabbit.
What is the probability of an offspring being black?
A. 25%
B. 50%
C. 75%
Answer
A. 25%
Explanation:
This is because the black hybrid would be 50% one breed and 50% another breed. Then the white purebred is 100% one specific breed. So by mating, all of those breeds that the parents have all reduce by 1/2 for the offspring.

why is kidney cell different from other cells in your body ? what role do stem cells play?
Answer:
1. Cells have different shapes because they do different things. Each cell type has its own role to play in helping our bodies to work properly, and their shapes help them carry out these roles effectively. The following cell types all have unusual shapes that are important for their function. 2. Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells
Explanation:
Kidney cell is different from other cells in your body such that they are
involved in the following functions due to unique structures and
mechanisms present.

Students were investigating the movement of water through a semi-pern
with the salt concentration shown below.
Answer:
It depends on the salt concentration inside the cell.
Explanation:
The movement of water through a semi-permeable membrane with different salt concentrations depends on the amount of water and salt concentration in the cell. If the cell has more salt concentration so no more salt moves inside the cell but moves outside the cell while on the other hand, if the cell has low amount of salt than the outer environment then the salt moves inside the cell until its concentration are equal.
where should buildings be constructed if we want them to survive major earthquakes
Answer:
Engineers must design in structures that can absorb the energy of the waves throughout the height of the building.
Explanation:
What evidence is there that all living things are made of cells?
A cell can be described as the structural and functional unit of life. It can also be described as the building material of all living organisms.
Without the cell, most living organisms will not be able to function. An organelle will not be able to survive that long within its life span without the presence of cells. It will just withe and die off.
Lots of scientists have proved in various ways the existence of cells, this is because they have been able to create microscopes that can see these tiny cells. This is evidence that proves the existence of cells.

The apple reflects red light and absorbs all other visible wavelengths. The apple absorbs red light, and reflects all other colors of light.. The apple is absorbs all visible wavelengths, but absorbs red light better The apple is reflects all light that hits its surface.
Answer:
The apple reflects red light and absorbs all other visible wavelengths
Explanation:
The apple is only reflecting the color red and is absorbing the other colors of light (wavelengths)
The correct explanation why an apple looks red is that the apple reflects red light and absorbs all the other visible wavelengths. Thus, the correct option is A.
What is Absorption and reflection of light?Light absorption is the process in which the light ray is absorbed by the matter and converted into a form of energy. In an atom, the electrons vibrate at a specific frequency, then this is called as the natural frequency.
Reflection is a phenomenon of light. When a ray of light approaches a smooth polished surface such as metal and the light ray bounces back, it is called the reflection of light. The incident light ray which land on the surface is reflected off from the surface. The light ray that bounces back is called the reflected ray.
Therefore, the correct option is A.

The cell theory is a scientific explanation about the characteristics of cells in living things discovery of cells occurred in the 1600s which piece of equipment my students in science class used to investigate the cell theory
Answer:
Then, what is the question????
In 1665, Robert Hooke, a scientist published Micrographia, a book full of illustrations and descriptions of organisms observed under the recently invented microscope, hence Hooke's discovery of the cell was successful with the invention of the microscope.
What is Microscope?A microscope is defined as a laboratory instrument used to examine objects that are too small to be seen by the uncovered eye. Microscopy is the science of examining small objects and structures using a microscope. The word microscopic means invisible to the eye unless aided by a microscope.
Without the microscope, we would not know about the existence of cells or how plants breathe or how rocks change over time. Cell theory was discovered by Robert Hooke in 1665 with the help of a microscope.

Explanation:
Weathering can be explained as the
breaking down of rocks as well as minerals or dissolving it on the surface of the earth. After the rock has been broken down then the bits of the rock can be transported away in a process known as " Erosion". The agents of
weathering and erosion could be water, salt, animal as well as plants.
It should be noted that the parts of sedimentary rocks formation that include the breakdown is weathering while the parts of sedimentary rocks formation that include carrying away of existing rock is erosion.

Generally, sessile organisms are those that live their life attached to a substrate and, therefore, are not able to freely move about.
Answer:
True

How was early Earth's atmosphere different from today's atmosphere?
Answer:
The early Earth was very different from our Earth today.
Explanation:
Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air (Figure 12.13). These gases created a new type of atmosphere for Earth.
Answer:
The atmosphere we enjoy today is radically different from the atmosphere that formed with the Earth billions of years ago. ... As the Earth cooled enough to form a solid crust (4.4 billion years ago), it was covered with active volcanos. These volcanos spewed out gasses, like water vapor, carbon dioxide and ammonia.
How has the Earth's atmosphere changed over time?
Water vapor, carbon dioxide, methane, ammonia, and other gases similar to the ones produced by volcanoes today were expelled. Over a vast amount of time, millions of years, the earth gradually cooled. ... From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.
