Place in order the correct sequence by which water flows through plants
1. transpiration from the leaves
2. absorption from the soil by root hairs
3. movement from roots to stem
4. flow upwards in the stem
Answer:
The correct sequence is - 2, 3, 4, 1.
Explanation:
The movement of the water takes place in the plant from the soil and moves up to leaves and from there to the atmosphere. Root hairs help in the absorption of the water from the soil with help of the epidermis of root hairs. Water then takes the path from the root to the stem with help of cortical cells.
Once the water reaches the endodermis or endodermal cell the water freely flow in the xylem cell upwards the stem moves to leaves by the transpiration stream. In the process of transpiration, an excess amount of water evaporates into the atmosphere.
Explain how breast-cancer genes are still present in the population, despite cancer-related surgeries and deaths.
Answer:
the correct answer would be - inheritance.
Explanation:
BRC1 is one of the genes that cause breast cancer which is thought to be inherited from the parents and even surgery can remove it from the person or it removed with the death of the person but genes already passed on next generation.
Surgery can not remove the gene but the tumor only and can reappear again. It is impossible to remove the complete gene from the population.
each of these statements is a key characteristic of science, except: group of answer choices science focuses on explaining the natural world. science is based on the premise that things and events that happen in the natural world occur in consistent patterns that are comprehensible through careful systematic study. science is a process for producing knowledge which may be abandoned or modified in light of new evidence or reconceptualization of prior evidence and knowledge. scientists will never seek additional data once they confirm a hypothesis. both c and d.
Answer:
scientists will never seek additional data once they confirm a hypothesis
Explanation:
All the options are characteristics of science except the one that says that scientists will never seek additional data once they confirm a hypothesis.
That a hypothesis is confirmed does not mean that scientists are done and dusted with that phenomenon. One of the reasons the experiments that are used to test hypotheses are usually reproducible is to allow for continuous testing even after hypotheses have been confirmed. Continuous confirmation of hypotheses by many independent researchers turns the hypotheses into law and from there, theories can become laws when they are overwhemingly accepted worldwide and test against a wide range of phenomena.
Generally, science is a process of producing knowledge about the natural world. A previously held belief in science can be abandoned or modified once new evidence emerges
The validity of scientific theories and laws depends on evidence. Which of the following statements of evidence supports a law rather than a theory?

As one moves from left to right across the periodic table, what trend are evident?
A.) Atomic radius increases moving left to right
B.) Nonmetallic character increases moving left to right
C.) Electron affinity increases across the periodic table
D.) Elements change from solids to liquids and then gases.
E.) Most reactive elements on left and least reactive in n the right.
Answer:
C
Explanation:
Moving from left to right across a period, atoms become smaller as the forces of attraction become stronger. This causes the electron to move closer to the nucleus, thus increasing the electron affinity from left to right across a period. Electron affinity increases from left to right within a period.

Explanation:
A fungus with white spores cross fertilizes a fungus with black spores. If 10% of the progeny bear white spores while 90% of the progeny bear black spores, what must be true?
A.
The trait for spore color is determined by exactly one gene.
B.
The trait for spore color is determined by more than one gene.
C.
The allele for black spores is dominant over that for white spores.
D.
The allele for white spores is dominant over that for black spores.
Answer:
C. The allele for black spores is dominant over that for white spores
Explanation:
Since there are more of an outcome of black spores it would make sense that this trait is dominant.
White spores seem to be recessive in this case too.
It is also suspected that the parents are both heterozygous. They both carry one trait for black and one for white.
What type of proteins speed up chemical reactions?
1. What must be true to have offspring with black fur?
2. What must be true to have offspring with white fur?
3. What must be true to have offspring with black eyes?
4. What must be true to have offspring with red eyes?
5. What must be true to have offspring with red eyes and white fur?
Answer: Genetics
Explanation: This may sound a little strange, but in order to have animals with certain traits, they must be born with or have in the blood line to have said traits. Even then the traits exhibited may not be hereditary. There is a 50% chance that the genetics that you want the offspring to have, may not occur. When a child is made, this means that the parents donate chromosomes from both sides to give the child some of their looks. This could mean disease, eye color, hair thickness.
Answer:
1) At least one dominant allele
2) Two recessive alleles
3) At least one dominant allele
4) Two recessive alleles
5) Pure recessive

While pushing a wagon around the park steve applies a force of 100n along thd handlr which makes 32cangle with the ground if he pushes it 25 metree how much wrk dods he fo
Answer:
Workdone = 2120 Joules.
Explanation:
Given the following data;
Force applied = 100N
Angle = 32°
Distance = 25m
To find the workdone by Steve, we would first of all find the horizontal component of the force applied.
[tex] Horizontal force, Fx = mgCosd[/tex]
Where;
Fx represents the horizontal force.
m is the mass of an object.
g is the acceleration due to gravity.
d is the angle of inclination (theta).
mg = weight = 100N
Substituting into the equation, we have;
[tex] Fx = 100 * Cos32[/tex]
[tex] Fx = 100 * 0.8480[/tex]
Fx = 84.80N
Workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
Substituting into the equation, we have;
[tex] Workdone = 84.80 * 25 [/tex]
Workdone = 2120 Joules.

Which of the following situations is an example of artificial selection?
O A farmer breeds cows, developing larger, more muscled calves
O A species of mouse develops lighter fur, reducing the likeliness that it will be seen by predators.
O A species of spider develops the ability to produce thousands of eggs, ensuring that some of its offspring
will survive.
O A species of anteaters develops narrower snouts, making it easier to eat ants in their anthills
Answer:
A
Explanation:
Because we people select cows for breeding for their traits of big muscles and producing lots of milk so us humans artificialy seselct these healthy cows for their traits
The correct answer is option A farmer breeds cows, developing larger, more muscled calves.
What are artificial and natural selection?Artificial selection is a measure taken by humans to identify desirable traits of plants and animals and to improve and maintain those traits in future generations.
Natural selection is natural selection, and artificial selection is human selection. The main difference between natural selection and artificial selection is that natural selection produces a large amount of biodiversity, whereas artificial selection produces the following types of organisms. B. Improved crops and livestock.
