How do limited abiotic resources impact the overall biotic organisms in an ecosystem?
Answer: Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. ... Limiting factors keep populations within an ecosystem at a certain level. They may also limit the types of organisms that inhabit that ecosystem.

The user needs to drag the slider bar in an upwards direction in order to completely melt away a body layer when in the dissection study area.
True or False
Answer:
False
Explanation:
During the dissection study the body is kept in laying position so that the scientist can easily perform experiments. The body is kept in laying position not in upward position. The body in upward position will have gravitational effect on the fluids and the body layer will not melt.
There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiply the series of dilutions together to find the final dilution value. If 6 serial dilutions are performed, each with a dilution of 0.1, what is the cumulative dilution
Answer:
cumulative dilution = 0.000001
Explanation:
A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.
The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:
Cumulative dilution = (F)ⁿ
where:
F = dilution factor = 0.1
n = number of serial dilutions = 6
∴ cumulative dilution = (0.1)⁶ = 0.000001

Claim: Warmer weather caused Galetown to have more severe storms.
can you explain why this happens please?
Answer:
Warmer weather caused Galetown to have more severe rainstorms. When the temperature of an air parcel starts out higher, it will have to rise higher in the troposphere before the temperature of the air parcel and the surrounding air are equal. When the temperatures become equal the air parcel will stop rising.
Explanation:
Answer: When the temperature of an air parcel starts out higher, it will have to rise higher in the troposphere before the temperature of the air parcel and the surrounding air are equal. When the temperatures become equal the air parcel will stop rising.

leaves of cactus are modified into thorns
Answer:
To reduce loss of water through transpiration leaves of cactus plants are modified into spines.
Explanation:
Answer:
leaves are reduced to spines in a cactus , so that the water does not get evaporated with the heat of the SUN. 1. They are present in hot deserts which are scarce in water so in order to reduce the loss of water by Transpiration from the surface of the leaves, its leaves are reduced to spines
Why do viruses not fit easily into the broadest taxonomic category, life? (Choose all that apply)
1. They are not made of cells.
2. They have a capsid.
3. They do not reproduce on their own.
4. They do not respond to stimuli.
Answer:
viruses are not fit into broadest taxanomic system because:
they are not cells
they do not reproduce their own
they do not respond to stimuli.
Explanation:
viruses have capsid and are not cells. to be a cell they must have a cell membrane while viruses lack cell wall. they replicate by using the host machinary in which they are causing infection. they are acellular and obligate intracellular parasites of anials plants fungi and bacteria.
Answer:
they are not cells
they do not reproduce their own
they do not respond to stimuli

This picture shows different amounts of space in between the particles of two
different soil samples.
Which word best describes what we are seeing?
Answer:
Porosity
Explanation:
I had another question like this and it was B so there u go
Meaning of soil porosity: Pore-spaces, also known as voids, are the area of the soil's volume that is not occupied by solids, either mineral or organic, hence option B is correct.
What is soil porosity?
Under field conditions, air and water are always present in the pore space. The amount of water that a specific volume of soil can hold depends on the amount of pore space.
How many pores, or holes, a soil has is referred to as its porosity. A proportion of the total volume of the soil material is used to measure a soil's porosity.
Soil particles are defined as those that are 2 mm in diameter or smaller and make up the inorganic component of soil. Sand, silt, and clay are the three types of soil particles.
Therefore, Porosity is a crucial indicator in locations where groundwater reserves supply drinking water.

show variation?
Answer:
gugkugcoytci6r
Explanation:
Causes of Variation:
Causes of differences between individuals include independent assortment, the exchange of genes (crossing over and recombination) during reproduction (through meiosis) and various mutational events. There are at least three reasons why genetic variation exists between populations.

Sequence of dna that is not involved in coding for a protein
Answer:
Transfer RNA, Ribosomal RNA, and Regulatory RNAs
Explanation:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules.
Answer: Ribosomal RNA, Transfer RNA, and Regulatory RNAs.
Explanation: The introns do not code for any protein and are removed from the mRNA before it is made into protein.
All of the following are characteristics of cancer cells except
a. No apoptosis
B. Ability to metastatize
C. Angiogenesis
D. Unregulated mitosis
E. Unmutated DNA
Answer:
i think it is c
Explanation:
The option that is not characteristics of cancer cells is E (Unmutated DNA).
Cancer is caused mutations or abnormal activation of cellular genes that control cell growth and cell mitosis.
The characteristics of cells that are cancerous include:
No apoptosis: Apoptosis is programmed death of a normal cell. This doesn't occur in cancer calls as the cells continue to divide giving rise to malignant cells.
Ability to metastatize: This is the ability of cancer cells to migrate to other normal cells and tissues of the body. This so because they are less adhesive to one another.
Angiogenesis: This is the ability of cancer cells to form new blood vessels that supplies blood to it for its nourishment.
Unregulated mitosis: This is the ability of cancer cells to grow without the usual cellular growth limits.
Mutation is the abnormal changes that occur in the deoxyribonucleic acid of a cell.
Cancer cell develop due to mutation of antioncogenes, which are genes present in cells which suppress the activation of oncogenes that lead to cancer.
Therefore, the option that is not a characteristics of cancer cells is E (Unmutated DNA).

g One benefit of operons in bacteria is that they a. do not need ligands and regulatory proteins as single genes would. b. do not need any modification of the proteins after they are expressed. c. allow for alterations in DNA sequence by flipping promoters around. d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter. e. allow the bacteria to use a wide variety of carbon sources.
Answer:
d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter.
Explanation:
An operon is a group of functionally-related genes that share the same promoter region and the same operator which interacts with specific repressors or activators, and they are transcribed as a unit. This transcriptional unit (operon) is present in prokaryotic organisms (i.e., bacteria and archaea) but absent in eukaryotes. In an operon, each structural gene is known as a cistron, and they are transcribed together as a polycistronic primary messenger RNA (mRNA).

Which of the following describes how the pollen must travel in order for pollination to occur?
Question 11 options:
. from the stigma to the anther
from an anther to the style
from an anther to the stigma
from the stigma to the pollen tube
Answer:
ewan the anther to stigma pero dapat stamen to the stigma
Answer:
I believe the answer is "from an anther to the stigma"
Explanation:
Because to be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.
