In farmland areas poor drainage can lead to a buildup of salt in
water supplies. A student performed an investigation to study the
effects of salinity on the germination rates of seeds. The student
places seeds in several solutions containing 0% to 3% salt. The
data from this investigation is shown below and suggests that
increased salinity in more areas may lead to a decrease in which of
the following?
Answer:
food production.
Explanation:
food plants need water to survive. Salt soaks water from a source of it If the slat buildup occurs in that water supply then the plants will not have anything to use to get their glucose to make food. This then leads to the con of the plants dying and the people having a loss of food production.

The passing on of genes from parents to their offspring is known as
Answer:
Heredity
Explanation:
there is no explanation for this
Answer:
"Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring"
A mutation that could be inherited by offspring would result from-?
Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.
What is mutation?Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.
As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.
Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.
Thus, the correct option is D.

Cells are often compared to factories. How is a factory a useful model for explaining the cell?
Answer:
Each organelle within the cell has its own important job, similar to factory workers. Every organelle plays an important role and without one, the whole team loses function.
Cell is the basic unit of life. Cells unite together and forms tissue. Many tissue will unite and form organ. Organ will unite together to form a organ system.
What is cell?The building elements known as cells make up all of these plants and animals, including worms in the soil, horseflies on farms, lemurs in the jungles, reeds in ponds, and trees in forests.
Similar to these instances, many live organisms are composed of numerous cells working together. However, certain forms of life, such as the various bacterial and protozoan species, are made up of simply one cell.
Most cells, whether they are solitary or a component of a multicellular organism, are too small to be seen without a light microscope.
Therefore, Cell is the basic unit of life. Cells unite together and forms tissue. Many tissue will unite and form organ. Organ will unite together to form a organ system.

In order for two new cells to be created during mitosis, each cell must receive an identical copy of DNA. In order to accomplish this task efficiently prior to mitosis, a cell will condense DNA into
Answer:
chromosomes
Explanation:
A cell must condense DNA into chromosomes before it can divide mitotically to form two new cells with identical copies of DNA.
The condensation of the DNA happens at the initial phase of the mitosis - the prophase - during which the DNA thickens and condenses to form chromosomes.
These chromosomes then align at the cell's plate during metaphase and they become separated into sister chromatids through the pulling of the spindle fiber at anaphase. Separated chromatids of the same chromosome are then transported to the opposite ends of the cell where they decondense before cytokinesis takes place.
1. Explain the pathway of Endosymbiosis, and explain the job of all the organelles involved.
Answer:
All living things are made up of cells. Even though there are many millions of life forms on earth, all of them are made up of only two basic types of cell: prokaryotes and eukaryotes.Cells contain DNA. Prokaryotes (pro-carry-oats) are small and simple and have rings of circular DNA floating free inside the cell. Eukaryotes (you-carry-oats) are large and more complex.

write four observable differences between rat and toad
Answer:Frog or toad: how to tell the difference
Skin
If there was ever a tell-tale sign to indicate which amphibian you are looking at, it’s the texture of their skin. Toads are warty-looking, covered in little lumps and bumps, while frogs are sleek and smooth. Toads also virtually always have dry skin, whereas frogs look wet even when they are out of the water.
Location
If you’ve spotted an amphibian making its way along a pavement or ambling through some grass, chances are it’s a toad. Toads cope much better with dry conditions than frogs, as their skin is more waterproof. Frogs lose moisture a lot more easily, and so are rarely seen too far away from water, which explains why they always look moist.
Legs
Frogs have long legs, longer than their head and body, which are made for hopping. Toads, on the other hand, have much shorter legs and prefer to crawl around rather than hop.
Explanation:
Answer:
1. color.
2. texture and or roughness. the rat will be smooth and the toad will feel rough against the skin.
3. growth/ size. rats can grow to be huge and toads tend to stay kind of small.
4. rat has a tail and toad does not.

Explanation:
Write this!
If you were to place a seed down horizontally, the roots and the shoot will be grown horizontally, but when the plant grows, it will slowey become less horizontal as time flies by and shape back into a straight manner towards the sunlight, this would be a example of a term known as geotropism (the response of plants from gravity).
Construction workers attach ropes and pulleys to wooden timbers on an old bridge.
They use the rope and pulley system like the one in the diagram below to move the
timbers away from each other, in order to dismantle the bridge.
Answer:
It is a safe and efficient method.
Explanation:
This method of dismantle the bridge is also a good one but there are some other methods also that are used instead of rope and pulley system such as destroy the bridge by using bombs at the base of pillars and cutting of each part in order to dismantle the bridge. This rope and pulley system is also an efficient way to dismantle the bridge so that's why the engineers used this method instead of other methods due to its safe method.

If more individuals are born with the advantageous trait in each generation, over time what do you predict will happen to the percentage (%) of the alleles (gene variety) that code for this trait in the population?
Answer:
The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.
Explanation:
The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.
