<span>Answer B, skin, is an example of epithelial tissue. All other answer are examples of different types of tissue; Bone being osseous tissue, fat being connective tissue and muscle being muscle tissue. Nervous tissue is one of the types that has cells that expand across the entire human body. Nerves can be both long and reach every corner of the body. The other type of tissue that can cross the entire body is epithelial. This type of tissue does not produce large cells that span great distances on/in the body. But, these cells do provide the lining throughout the body and are the tissue that makes up the protective layer called skin. Both connective tissue and muscle tissue form large amounts of tissue in the body but they do not expand to all reaches of it.</span>
Answer:
Velocity = 2m/s
Explanation:
Given the following data;
Mass = 8kg
Momentum = 16kgm/s
To find the speed;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
Substituting into the equation, we have;
16 = 8 * velocity
Velocity = 16/8
Velocity = 2m/s
Therefore, the bowling ball is traveling at the rate of 2 meters per seconds.
Answer:
There are different evidences for evolution that includes anatomy, fossils, molecular biology and biogeography.
Molecular biology uses DNA and protein sequences that the genetic code reflect the shared ancestry of life. DNA comparisons used for the anatomical evidence.
All living cells are organized in the same basic DNA and use the same genetic code. Proteins derived from genes, all originate from the same set of amino acids. Comparing parts of DNA in various species has shown that even very different organisms still have significant parts of similar DNA. For example, in chimpanzees and humans have some precent of same genetic structure. In the amino chain, chimpanzees and humans have only one position, while humans and moths have 31 different positions.
<u>There are different advantages and disadvatages of each type of evidences are:</u>
Advantages:
- Anatomy share information about the similar physical structures shared by common ancestor (homologous structures)
- Fossils provide information about the extinct species.
- Molecular biology provide genetical relationship between organisms.
- Biogeography share global organism distribution and island species unique characteristics reflect evolution and geologic change.
Disadvantages:
- some of the structures such as forelimbs of human and birds seems homologous in structure as per comparative anatomy but they have evolved independently in each species.
- Fossils are impressions of past living organism and buried in earth surface rom long geological past, hence during this geological time there can be many changes in the fossil structure and can manipulate the evidences.
- Molecular biology has disadvantage of lack of assay specificity and sensitivity.
- organism can evolve and adapt according to different condition, hence Biogeography can not exactly tell the exact changes in the characteristics of organisms on the basis of particular geology.
Explanation:
They grow through a combination of cell growth and cell division (mitosis). The key plant growth is meristemn, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Meristem allows plant stems and roots to grow longer (primary growth) and wider ( secondary growth ).
