Answer:
A. Contain cells that connect to form pipes.
B. Transport water and food.
Explanation:
The vascular tissue is known to be conducting tissue which has more than one cell type. It is usually found in vascular plants. It is composed of xylem and phloem.
Their function is to transport fluid (like water) and other nutrients, therefore they have cells that connect to form pipes. The xylem and phloem occur together in vascular bundles in the plant organs passing through stems, leaves and roots.

What is Cladogram?A cladogram is a representation of a potential link between groupings of species, including their shared ancestors. The Greek terms "clados" and "gramma," which mean "branch" and "character," respectively, are the origin of the words "cladogram."
The image gives the impression that a tree trunk is sprouting branches. Yet, the cladogram's form is not necessarily vertical. The diagram's sides, top, bottom, and center can all branch off of it.
Cladograms can be exceedingly complicated, potentially classifying all forms of life, or very simple, comparing only a few types of organisms.
Therefore, The frog has 2 limbs at the back and 2 on the front. a pigeon walks with its two tiny legs.

If all of the characteristics of life are required to classify something as “alive”, how can we account for those individuals who are definitely alive, but that do not reproduce (for example, people without children or a sterile mule)?
Answer:
Here is the answer key. Just scroll down to the question and the answer is there.
Explanation:
These organisms are still alive. Reproduction is not important for survival but for the survival of a species.
What is the importance of reproduction?The only way to ensure that the kind of species survives and keeps flourishing on the planet is through reproduction. The process by which organisms give rise to new offspring is called reproduction. It is one of the many defining characteristics of life and loving organisms.
There are some organisms that look and act exactly like their parent/parents. Whereas, other kinds of organisms share similar traits with their parents but are not completely like them. These organisms are unique individuals in their various characteristics.
Some species have two parents, whereas others have just one. It is determined by the method of reproduction by these organisms. It also determines the percent of similarity of the organism with its parents.
Reproduction is basically of two types: asexual reproduction and sexual reproduction. Asexual reproduction involves the development of new organisms by a single parent. Sexual reproduction involves two parents and their fusion of gametes.
Therefore, Reproduction is essential for the survival of a species and not for the survival of an organism.

Fill in each blank with the type of energy being described
The sun gives off ____energy, which enters the atmosphere. Plants absorb some of the energy
and perform photosynthesis to convert it into____energy in the form of sugars. Plants and the
animals that eat them then turn that energy into a different form of ____
energy, in the form of
ATP. When plants and animals use the energy, it becomes ____ energy
Explanation:
Solar
light
Chemical
Kinetic
The sun gives off HEAT energy. Plants convert it into CHEMICAL energy. Plants and animals turn that energy into a different form of CHEMICAL energy. When plants and animals use energy, it becomes KINETIC energy.
Photosynthesis refers to the chemical reactions by which plants use heat energy from the sun to create chemical energy in the form of chemical bonds of sugars.
Both animals and plants perform a series of metabolic reactions collectively known as cellular respiration.
Cellular respiration refers to the reactions by which plants and animals produce chemical energy in the form of ATP, the energy coin of the cell.
Finally, kinetic energy is the energy associated with motion both in plant and animal cells, which is required to carry out metabolic functions (e.g., reproduction, growth, differentiation, etc).
In conclusion, the sun gives off HEAT energy. Plants convert it into CHEMICAL energy. Plants and animals turn that energy into a different form of CHEMICAL energy. When plants and animals use energy, it becomes KINETIC energy.

what does gene versions mean?
Answer:
Basically, Its like a Different version of a gene which are called alleles. Alleles are described as either dominant or recessive depending on their associated traits
Explanation:
Answer:
These gene variants still code for the same trait (i.e. hair color), but they differ in how the trait is expressed (i.e. brown vs blonde hair). Different versions of the same gene are called alleles. Genes can have two or more possible alleles. Individual humans have two alleles, or versions, of every gene.
