state one adaptation of nephron in the kidney of a desert mammal
Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.
Explanation:
The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.

hope this helps :)
All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
What is the digestive and excretory system?Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.
The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.
The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).
Therefore, the correct answer is a).

A. Predation
B. Mutualism
C. Cooperation
D. Parasitism
Answer:
Parasitism
Explanation:
There is no mutual relationship (also meaning no cooperation, which I do not think is a type of relationship), the mite isn't "eating" the honeybee, so not predation. Therefore, parasitism, when one creature benefits at the expense of the other creature.

In 1859, Charles Darwin proposed that differential survival and reduction of individuals would produce changes in species population over time. In other words, the environment acting on variation of individuals within a population would result in an adaptation (an evolutionary process that results in morphological, physiological or behavioral changes at the population level and that increases the probability of the members of that population to survive and their reproductive success). Using a specific example, explain how natural selection explains the theory of evolution. Also include in your explanation and within your example, what are the 4 factors needed for natural selection to act
Answer:
Reproduction, heredity, variation in fitness or organisms.
Explanation:
Evolution occurs in organisms due to natural selection process because natural resources are limited. Evolution is the change in the characteristics of a species over several generations. If evolution occurs in the organisms so these evoluted organisms can survive rate more than those organisms where no evolution occurs because the evoluted organisms can adopt successfully the features of environment. Reproduction, heredity, variation in fitness or organisms are the four factors needed for natural selection to act.

similarities between the vas deferens of a male reproductive system and fallopian tube of a female reproductive system are ?
Answer:
Vas deferens → Male reproductive system
Fallopian tube → Female reproductive system.
Explanation:
In vertebrates, there are paired gonoducts for the movement of gametes from the gonads. Humans are no different.
1. Vas deferens is a male gonoduct that transports sperm away from the testes in preparation for ejaculation. Vas deferens collects secretion from seminal vesicle and becomes ejaculatory duct before draining in male urethra.
2. The fallopian tube is a female gonoduct that receives ova from the ovary when ovulation occurs. Fertilization occurs in the fallopian tube, and the early embryo moves from the tube to the uterine cavity.
3. Ciliated pseudostratified epithelium lines the vas deferens, while ciliated columnar epithelium lines the fallopian tube.

Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
How did the research of Miller and Urey contribute to the hypotheses about the origins of life on Earth?
Answer:
Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.
Explanation:
Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.
To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.

Check All That Apply Feeding behaviorFeeding behavior Adult body symmetryAdult body symmetry Ultimate adult body sizeUltimate adult body size The embryological formation of body cavitiesThe embryological formation of body cavities Biogeographic distributionBiogeographic distribution Gene sequencesGene sequences The number of tissue layersThe number of tissue layers
Answer:
The correct answer is -
Adult body symmetry
The embryological formation of body cavities
Gene sequences
The number of tissue layers
Explanation:
Scientists and taxonomists use different criteria to assign different animals to particular phyla. The various systematic criteria that are used more frequently by systematists are as follows:
1. Adult body symmetry
Body symmetry is one of the criteria used to assign an organism or animal to a particular phylum. There is two symmetry found in animals radial and bilateral. If any plane passes through the middle axis and divides into two identical segments called radial symmetry and Bilateral symmetry is where only a single plane divides the body into halves. However, there are many animals that do not have any symmetry and called assymetrical.
2. The embryological formation of body cavities
Other than layers body cavities also helps in assigning the animals that depend on coelom - body cavity between the body wall and gut wall
Animals could be - coelomate(coelom present), pseudocoelomate -(not lined with mesoderm) and acoelomate(coelom absent).
Gene sequences
Genetic similarities also consider and how close an organism to their organism of the phylum or species.
The number of tissue layers
Different body parts, tissues, muscles, and organs developed from the different cell layers that are formed during embryo, therefore, called embryonic layers.
Animals on the basis of these embryonic layers could be diploblastic or triploblastic. Diploblastic animals form 2 embryonic layers the outer and inner layers called the ectoderm and the endoderm respectively. Triploblastic animals have an extra middle layer known mesoderm.
A company called Sierra Pacific Industries is destroying forests by a destructive and non-sustainable practice called clearcutting. This is being done at an alarming rate in specific counties in California.
