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.

Explanation:

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.

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.

Answer:

The researchers performed a meta-analysis of 27 previous studies of how coral reefs around the world dissipate wave energy, conducted in conditions ranging from normal surf to hurricane-level waves. They found that coral reefs reduce wave energy by an average of 97 percent, dissipating disproportionately more wave energy as wave energy increased.

Answer:

Diffusion of solutes in liquids is very important in many industrial processes, especially in such separation operations as

1) liquid–liquid extraction or solvent extraction,

2) gas absorption

3) distillation

4) Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow

5)and lets them get rid of waste products.

mike arrived to work at 8:55 while Ashley arrived at 9:05

Explanation:

8:30 + 25 min = 8:55

8:15 + 50 min = 865 so that would be 9:05

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.

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.

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.

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

Total 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.

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.
