Cows have an incredible digestive system which is highly evolved to process grass in unique ways. Please research and write a short essay regarding the function of the 4 bovine stomachs and how they all work together to process complex carbohydrates. Be sure to include the function of the reticulum, rumen, omasum, and abomasum.

Answers

Answer: Ruminants have complex digestive system.

Explanation:

Rumen: It is a sac like structure and first region of the stomach of the cow. It is connected with the esophagus. It forms the storage of the food and convert the food in the form of ball called cud.

Reticulum: It is a honeycomb like structure. It is attached with rumen. It holds and stores the heavy and dense components of the food.

Omasum: It lined with folds of tissues. It absorbs water and nutrients form the food.

Abomasum: It is called true stomach as it operate similar to non-ruminant animals. It secretes hydrochloric acid and enzymes to break down and help in feeding food.

Most populations do not experience: ____ va) exponential growth b) Linear growth c) Resources d) Competition

Answers

Answer:

Most populations do not experience: a) exponential growth

Explanation:

Populations that experience exponential growth models show an increase in proportion to their size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.

This model states that populations live in an environment with unlimited resource availability, so the density factor does not influence population growth. There is no density-dependence effect nor competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita, and it is proportional to the population size.

Exponential growth is hardly seen in nature due to its characteristics.

Almost every environment shows a carrying capacity point. Carrying capacity is the capability of the environment to support a population. Commonly environments have limited resources and space, and as the population grows, competition increases too. The per capita growth rate decreases as population size increases. Finally, the population reaches the maximum point of carrying capacity, delimited by available resources, such as food or space.

The carrying capacity might be affected by limiting factors, which might be a result of the population density (for example, competition) or might be density-independent. This last case refers to dense-independent factors, and among these, we can mention human impact or natural disasters (fires, volcanic eruption, flooding).    

Only a few species can experience exponential growth, such as bacterias.

The production of egg and sperm cells follows a certain sequence of events.

Which example lists those events in the correct order?
fertilization, meiosis, cell differentiation


meiosis, cell differentiation, mature gametes


sexual reproduction, cell differentiation, mitosis


cell differentiation, meiosis, sexual reproduction

Answers

The production of egg and sperm cells follows a certain sequence of events.

The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.

Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.

Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.
