Answer:
based on the predominant movement of water molecules through the cells.
Explanation:
Cell processes and transport rely on the movement of water molecules through the cell membrane.
Cell transport describes the transportation of a material through a cell membrane. The molecule has the ability to enter or exit cells. The plasma membrane and cell membrane are both permeable to various substances. The nature of the plasma membrane is semi-selective which means it is semi-permeable.
There are four classifications of cell transport and those are simple diffusion, osmosis, facilitated diffusion, and active transport.

Many fruits can be preserved by candying. The fruit is immersed in a highly concentrated sugar solution, and then the sugar is allowed to crystallize. How does the sugar preserve the fruit
Answer:
By removal of water.
Explanation:
Sugar preserve the fruit by replacing some of the water in the fruit. This natural process preserves the fruit's original color, texture and shape by preventing remaining water of the fruit from leaving its cellular structures. Due to removal of water with the help of sugar from the fruit helps in preserving the fruits for long time period. The sugar helps in drying of the fruits so that's why we can say that sugar preserve the fruits.
a car moves takes in fuel releases energy from fuel gets rid of waste through the exhaust pipe is a car living thing
Answer:
The correct answer is - no, the car is not a living thing.
Explanation:
All living organisms have definite life processes that are characteristics of a living organism and are common in every living being. There are seven life processes that determined and need to do to count as a living thing, that are -
1. Movement - all living things show some type of movement, even plants
2. Respiration - required to get energy from food
3. Sensitivity - sense what is happening around
4. Growth - all living things grow
5. Reproduction - increasing number of the same type
6. Excretion - removal of biological waste
7. Nutrition - utilizing food
A car shows movement and the ability to get energy from fuel similarly as respiration and nutrition can show sensitivity if an alarm installed, and removes waste through exhaust pipes like excretion. However, it can not grow or make another same type like reproduction, So a car is not alive.
In this assignment, you will use simulations to analyze how climate, resources, and habitat size affect
carrying capacity. You will then look at another simulation to analyze the effects of certain factors that
affect biodiversity and populations. Finally, you will write and revise a conclusion on how human activity
affects biodiversity.
Background Information
Population growth is the change in size of a group of organisms of the same species over time. It is
affected by four factors: birth rate, death rate, immigration, and emigration.
Carrying capacity is the maximum total population that an area can support. Carrying capacity limits
population growth and is affected by competition for food, water, shelter, or mates, and threat of
predators, disease, and parasites. Carrying capacity may be affected by one or a combination of these
factors.
Biodiversity is the total variety of organisms that live in the biosphere. Biodiversity is affected by the loss
of habitat, introduction of invasive species, pollution, and/or human activities.
Answer:
Larger habitats support populations with higher carrying capacities. Higher quality habitats support populations with higher carrying capacities. There is no difference in population growth rate between large and small habitats. Some major threats to biodiversity are: Habitat destruction/Deforestation, Introduced and invasive species, Genetic pollution, Over exploitation, Hybridization, Climate change, Diseases, Human overpopulation. If abiotic or biotic factors change, the carrying capacity changes as well. Natural disasters can destroy resources in an ecosystem. If resources are destroyed, the ecosystem will not be able to support a large population. This causes the carrying capacity to decrease.
Carrying capacity could be reduced if each individual within the species consumed less from the environment. Think about humans: if every human needs a four car garage and a large house, the planet can sustain fewer humans than if each human lived in a studio apartment and traveled using a bicycle. It would take 1.75 Earths to sustain our current population. If current trends continue, we will reach 3 Earths by the year 2050. It is beyond dispute that the modern industrial world has been able to temporarily expand Earth's carrying capacity for our species. As Nordhaus points out, population has grown dramatically (from less than a billion in 1800 to 7.6 billion today), and so has per capita consumption. Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity. Sustainable agriculture practices support integrating biodiversity in various ways including in terms of diversity of crops, traditional agriculture techniques to control pests and increase productivity as well as ensuring that farmed land is made up of a diverse mix of grazing land, crop land, orchards, wetlands and more.

The result is an advantage of the green garden technology shown in the picture compared with other gardening practices is it conserves water.
There are both direct and indirect uses for water. Bathing, drinking, and cooking are examples of direct uses, while the production of steel for automobiles and the processing of wood for paper are examples of indirect uses.
Water is used by every cell, organ, and tissue in our bodies to keep our body temperature stable and maintain other bodily functions. Since our bodies lose water through breathing, perspiring, and processing, it's vital to rehydrate.

What is a Menstrual Cycle??
Answer:
The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that make pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the uterus to receive a fertilized egg. These cycles are concurrent and coordinated, normally last between 21 and 35 days in adult women, with a median length of 28 days, and continue for about 30–45 years.

Comprehensive detail and links between structure and functions of animal cells and different tissue in animals
Answer:
Great relationship.
Explanation:
There is a great relationship between the structure and functions of animal cells because the structure of cells helps the cell to perform a particular function assign to it. The cells in epithelial tissue are tightly packed together with a very little intercellular matrix. intercellular matrix is a non-living material used to fill the spaces between the cell. Due to this structure, the epithelial tissue forms the covering of all body and helps in protecting the skin.

Burrowing owls sometimes build their nests in holes that were dug by prairie dogs, coyotes, or badgers and have been since abandoned. They sometimes line the nests with cattle or horse dung. Why
Answer:
To avoid extreme temperature and keep away predators.
Explanation:
Burrowing owls sometimes line the nests with cattle or horse dung in order to avoid extreme temperature. The cattle dung protect the Burrowing owls from extreme temperature of the surrounding so they make nests close to these cattle dung. These dung has many insects which is a food of Burrowing owls and this cattle dung also keep predators away from Burrowing owls.

It has been proposed that the presence of black markings on the throat of kung fu geckos is coded by a dominant allele (B) and that the absence of such markings is coded by a recessive allele (b). To test this idea, heterozygous individuals are crossed (Bb x Bb) producing 500 offspring of which 350 have black markings and 150 don’t have black markings. Based on a punnett square, the expected phenotypic ratio for black markings to no black markings is 3:1.
Required:
Write down the correct statistical approach to test if the data is consistent with the expected 3:1 ratio.
Answer:
See the answer below
Explanation:
The correct statistical approach to test if the data is consistent with the expected 3:1 ratio would be the Chi square.
Chi-square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = Expected frequency. In this case:
Phenotype O E Chi square
Blacks 350 3/4 x 500 = 375 [tex]\frac{(350-375)^2}{375}[/tex] = 1.67Non blacks 150 1/4 x 500 = 125 [tex]\frac{(150-125)^2}{125}[/tex] = 5Total Chi square = 1.67 + 5 = 6.67
Degree of freedom = 1
Tabulated Chi square = 3.841
Since the calculated Chi-square is more than the tabulated value, the null hypothesis is rejected and we conclude that the data is not consistent with the expected 3:1 ratio.

g Name and describe two possible pathogens that could be responsible. The spinal tap reveals the presence of Gram-negative cocci in the CSF. What would be the likely diagnosis
Answer:
Explanation:
The missing information describing the status of the sick sophomore student is attached in the image below.
The first question says we should name and describe the two possible pathogens responsible for such.
The two possible pathogens are:
Virus and Bacteria.
Recall that, the College student experienced a severe headache, nausea, vomiting, neck stiffness, and fever.
These highlighted symptoms are commonly caused by meningitis which is a bacterial infection.
Surgeons, surgical tools, and scrub nurses must all be sterile when doing surgery; If any infection arises provided all crucial measures were not taking into consideration, it would harm the patient and there will be a risk of meningitis as a result of this.
SImilarly, given that In the CSF, the presence of Gram-negative cocci is shown via a spinal tap; then the likely diagnosis would be that:
The patient has suffered from Neisseria meningitis.
This is because Gram-negative cocci are the most prevalent cause of infection in persons of this age group and In the Gram stain test, it has a dark red color.

A dispersion pattern that indicates that resources are abundant, evenly distributed with little interaction within individuals is:_______.
Answer:
Uniform dispersion pattern.
Explanation:
Uniform dispersion pattern is a type of dispersion pattern in which resources are present in abundant quantity as well as evenly distributed with little interaction within individuals. Due to abundant quantity of resources , the population of organisms increases that leads to more population of individuals in the ecosystem. Due to abundant amount of resources, there is less competition as well as interaction between individuals that are present at that time.
