Answer:
a simple stomach and a large cecum
Explanation:
Some small animals whose diet is prominent in vegetable matter, have an elongated cecum.
This segment of the digestive tract might be considered the first portion of the large intestine. It receives undigested material, and through the action of bacterial flora, is able to ferment this material and mix its contents with mucous substances to facilitate absorption. Through the walls, the organ can absorb fluids, salts, and nutrients.
The cecum size varies according to the animals. In small organisms, such as the new squirrel-like herbivore animal from the example, the cecum is enlarged. An elongated surface is useful for better digestion and absorption.

why does a rational producer reject the business in increasing stage
Answer:
In three stages of production to which are hold by the law of diminishing marginal returns the second stage is considered to as the rational stage of production as compared to the first and third stage this is due to the fact that this stage it comes out with the best assumptions for efficient and sustainable production, thereby the stage it simultaneously shows the positivity of the average products and marginal product hence, in the increase of labour the total production or outputs increased likewise with the same quantity of fixed factor, therefore this stage it gives direction to the producer on how the higher units of output can be produced.
Unlike the first stage to which it shows each additional variable could enhance more production and such this it signifies an increasing of marginal return but for this case it do not give out the direction in permanent production since labours are needed fewer and in the decrease in number of labour can brings about underproduction.
Also the third stage marginal return is frankly negative because in adding more variable inputs will further led into adding more number of labour hence the increase of labour will contributes to under production as it may be due to labour capacity and efficiency concern.

What are the mechanism that use to resist the antimicrobial agents?There has been several mechanisms, like resistance to antimicrobial agents, encapsulation or secretation of proteins that affects and might destroy the phagocyte along with some leukocytes in our body perform phagocytosis as a defense mechanism against the pathogenic bacterium.
These phagocytes contain lysosomes, intracellular granules that possess bactericidal substances. When the phagocyte ingests the pathogen, a phagosome is formed, which merges with the lysosome, forming the phagolysosome, which is where toxic substances and enzymes kill the ingested microorganism.
There are several mechanisms by which a microorganism can survive this process as resistance to antimicrobial agents. Some bacteria use phenolic glycolipids from their cell wall, to eliminate toxic oxygen compounds.
Therefore, You can get infected with hand, foot, and mouth disease if you have the virus on your hands and then touch your eyes, nose, or mouth.

Mr. L was walking through the woods wearing shorts and sandals. He noticed a small tick on his ankle the same evening, and several weeks later he developed flu-like symptoms. A sample of his blood revealed the presence of long, wavelike cells that were twisting and waving. Based on the microscopic findings, which type of microorganism is responsible for Mr. L's symptoms
Answer:
Protozoa
Explanation:
The long, wavelike cells seen under the microscope would most likely be protozoa and the microorganism responsible for Mr. L's symptoms.
Tick as a vector is capable of causing diseases such as lyme disease, anaplasmosis, babesiosis, Powassan virus disease, tularemia, and a host of other diseases. Among all the diseases, babesiosis is particularly caused by a protozoan known as Babesia microti and it elicits malaria-like symptoms in individuals. Most of the other diseases are caused by bacteria pathogens while a few are caused by virus.
Apart from the above, the morphological characterization of the microorganism responsible for Mr. L's disease is typical for protozoans. Many of them are long and flagellated with a wave-like motion as a movement.
Hence, the case of Mr. L would be that of protozoa.

1. How are wavelength, frequency, and energy related to each other?
Answer:
wavelength: the distance between successive crests of a wave
frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
electromagnetic energy is used for wifi, cell phones, microwave ovens etc.
the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays
the only part we can see is visible light
visible light can be characterised by the colours of the rainbow
the longest wavelength is red and the shortest is violet
when combined, the colour is perceived as white or beige
Answer:
Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
Explanation:
WAVELENGTH=

2.
a person's ideas and way of thinking, especially as it affects their ability to communicate with others.
"when we met we hit it off immediately—we're on the same wavelength"
FREQUENCY=
Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
ENERGY=
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.
A population of 100 sea stars is in Hardy-Weinberg equilibrium. The trait for long arms is completely dominant to the trait for short arms. In this population, 40% of the alleles for this trait are dominant, and 60% are recessive. What percent of sea stars in this population are heterozygous
Answer:
In population genetics, the Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences
Explanation:
An allele frequency is computed by dividing the total number of copies of all the alleles at that specific genetic locus in the population by the number of times the allele of interest is observed in a population. The decimal, percentage, or fractional forms of allele frequencies are all acceptable.
What sea stars are in Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium, model, theorem, or law of population genetics states that, in the absence of additional evolutionary factors, allele, and genotype frequencies in a population will remain constant from generation to generation.
Therefore, The lesson and figure 12.12's allele frequencies are used in this question as well. The percentage of individuals with two dominant arm length alleles can be calculated by multiplying 0.6 by 0.6. The population size (100 people) multiplied by that percentage yields the number of people that are homozygous dominant for the arm length allele.
