What type of climate is experienced by cities that are close to large bodies of water as compared to inland cities at the same latitude?
Bigger changes in temperature and lower levels of precipitation. X
Hotter temperatures and a bigger range of different types of precipitation.
Milder temperatures and higher levels of precipitation. X
Much lower temperatures and lower levels of precipitation.
its not a or c so its b or d
science
Answer:
C
Explanation:
Being on the coast will result in milder temperature fluctuations because the nearby body of water helps regulate any big changes a city might occur. Being near the coast where lots of water is evaporating and forming clouds which then move inland and precipitate or rain, often fairly close to shore.
If this is on a self grading assignment the answer programmed may be wrong if it says C is wrong.
Approximately how many kilograms (kg) of carnivore (secondary consumer) biomass can be supported by a field plot containing 1000 kg of plant material?
About 10 kilograms (kg) of carnivore biomass can be supported by a field plot containing 1000 kg of plant material.
What is an ecosystem?An ecosystem is a self-supporting system consisting of living and non-living components.
In an ecosystem, a carnivore is a secondary consumer.
In energy flow in an ecosystem, 10% of biomass is transferred from primary producer to primary consumer, 10% from primary consumer to secondary consumers.
Thus, 1% of energy is transferred to the carnivore.
1% of 1000 kg = 10 Kg.
Therefore, 10 kilograms (kg) of carnivore biomass can be supported by a field plot containing 1000 kg of plant material.

Pea plants can have yellow seeds or green seeds. which conclusion about the meaning of y is correct if the allele combination yy is for yellow seeds? yellow and dominant green and recessive yellow and recessive green and dominant
Pea plants can have yellow seeds as the meaning of y is correct if the allele combination yy is for yellow seeds are yellow and dominant.
This question involves a seed color gene, which has two alleles Y and y. Y, which represents the dominant allele codes for the YELLOW trait while y which represents the recessive allele codes for the GREEN trait. Therefore, a plant with Yy will have YELLOW SEEDS because the dominant Y allele is present.
What are two alleles?Gregor Mendel has stated that a gene comes with two alleles. According to his law of dominance, one of the alleles called the DOMINANT allele is capable of masking the phenotypic expression of another allele called the RECESSIVE allele.
Thus it is clear that yellow and dominant are the meaning of y is correct if the allele combination yy is for yellow seeds.

What evidence will you look for during this experiment to help you determine the best concentration of saline for your patient?
(principle of biomedical science, activity 3.2.2.)
To help you determine the best saline concentration for your patient, it is necessary to know the dilution factor.
How to find the dilution factor?You can identify a solution dilution by the amount of solute in the total volume, expressed as a ratio. For example, a chemical substance can be prepared in a 1/10 (1:10) dilution of alcohol, indicating that a 10mL vial contains 1mL of the substance (solute) and 9mL of alcohol (diluent).
With this information, we can conclude that to help you determine the best saline concentration for your patient, you need to know the dilution factor.

Name two ways that a cell would be harmed if the cell membrane were damaged.
Answer:
Damaging the cell membrane like to impact the functions of the cell because cell membrane acts as a semi-permeable membrane which allows the entry and exit of some materials in and out of the cell. If the cell membrane get damaged then the cell wall allows every molecule to enter or leave the cell without selecting the molecules. Thus, the functional properties of the cell will lost and the cell will die.

how is an increased in carbonin the atmosphere likley to affect coastal areas such as those in north carolina
Answer:
D
Explanation:
The amount of Carbon dioxide (CO₂) that is trapped in the atmosphere is released by the burning of the fossil fuels and from the industrial pollution. In addition to this, some amount of it also released by the animals and human beings. This stored CO₂ in the atmosphere is then transported to the oceans with the help of rainfall. When this CO₂ reacts with water it forms weaker acid, which is commonly known as the Carbonic acid. Due to this, the pH level of ocean water decreases. As a result of this, it affects the ocean water chemistry and the marine life. Due to this ocean acidification, the marine species namely the corals and various types of planktons are not able to form the hard parts like the shell and skeletal parts. This carbonate water dissolves the existing shells and erodes the particles away. The increase in the carbon content in the atmosphere will also lead to precipitation that will wash away the rock particles and other sediments, that are present in the coastal areas. In addition to this, the plants also will be affected due to this carbon containing water.

The two main parts of evolution that Christians often try to reconcile with Scripture are the extent of change in organisms and the timetable of change. Fill in the following table, describing the different views of ori-
gins. The first row has been completed for you as an example.
Answer:
Explanation:
Why has Darwin’s science been such a religiously troubling idea? In those parts of the world influenced by the Bible and the Qur’an, we may point to at least five reasons: (1) Darwinian biology tells a whole new story of creation, one that cannot be literally reconciled with religious creation stories such as those narrated in the book of Genesis; (2) the evolutionary notion of natural selection seems to eliminate the role of God in creating the various species of life; (3) Darwin’s theory of human descent from nonhuman forms of life raises questions about traditional beliefs in human uniqueness, such as the biblical claim that human beings are created “in the image and likeness of God”; (4) the prominent role of chance or accidents in evolution raises questions about whether a creator truly cares for the world; and (5) the competitive “struggle for existence” inherent in evolution seems at odds with a Universe created by God.
Darwin's theory of human descent from nonhuman forms of life raises questions about conventional beliefs in human uniqueness, such as the biblical claim that human beings are the only species to have evolved from nonhuman life forms.
What kind of evolution that Christians often try to reconcile?Christians frequently attempt to reconcile two key aspects of evolution with Scripture: the pace of change and the scope of organismal change.
Darwinian biology tells a whole new story of creation, one that cannot be literally reconciled with religious creation stories like those narrated in the book of Genesis.
Therefore, the evolutionary notion of natural selection seems to eliminate the role of God in creating the various species of life.
