Answer:
1: C. They are found contained in a casing, called sporangia, and grouped into bunches, called sori, on the underside of the leaves.
2: C. The sporophyte generally releases spores in the summer. Spores must land on a suitable surface, such as a moist protected area to germinate and grow into gametophytes.
3: B: Moisture is needed for germination, growth and fertilization and high humidity for prothalli and young developing ferns after fertilization.
4: B. In ferns, spores are contained within cases called sporangia that are located on the underside of leaves.
5: C. Each spore grows into a photosynthetic prothallus (gametophyte) via mitosis. Because mitosis maintains the number of chromosomes, each cell in the prothallus is haploid.
6: D. the reason why that's the answer is because I read a national geographic paper and it said that spores can live for over a million years without maturing into an adult plant .
7: A and B. Walking fern also has another, asexual, way of reproducing. If the long extended leaf tip touches soil, a new plantlet can form at the tip, produce roots, and become a new plant. The new plant can then grow a long leaf which touches the ground and sprouts another plantlet. In this way the colony gets larger and larger.
I hope this helped, have a great day! :)

predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein
Full Question Attached
Answer:
The substance would be less likely to enter the cell by active transport or might enter more slowly
Explanation:
The information in the question suggests substance L is moving into the cell by active transport. We can tell this because the concentration of substance L inside the cell is 120 mM. However, the substance is still entering the cell from a lower to a high concentration, against its concentration gradient. This requires energy and is therefore active transport.
If there was a large protein attached, the active transport machinery might not be able to move substance L at the same rate. The rate it enters the cell might slow down, or it might stop all together. It might need to enter via another mechanism, such as endocytosis.
where do inherited traits come from and where do acquired traits come from (2 answers) ANSWER GETS BRAINLIEST!!!
Answer:
Inherited traits come from family members and are in your dna and Aquired traits you learn so are from other people.
Explanation:
Answer:
parent to offspring and during life
Explanation:
1. An inherited trait is one that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.
2.Acquired traits develop during life (organism is not born with it) . Animals learn these when they interact with environment. It is not in your DNA. It will not be passed on to next generation.
What chemical bond is responsible for the existence of the sugar-phosphate backbone of DNA
Answer:
Phosphodiester bonds
Explanation:
Answer:
The answer is phosphodiester bond.
Explanation:
The sugar phosphate backbone is an important stuctural component of DNA. It consists of 5-carbon deoxyribose sugars and phosphate groups. These sugars are linked together by a phosphodiester bond, between carbon 4 of their chain, and a CH2 group that is attached to a phosphate
what else is needed to make glycine (amino acid) from a molecule of glucose? Where do you think that comes from
Answer:
certain amino acids are made of different things but heres overall carbon hydrogen oxygen and nitrogen
Explanation:
Glycine is a naturally occurring/formed amino acid found in humans, the difference between glycine and other amino acids is that it can be found in parts of protein structures in humans and can also be found in several foods consumed by humans like Sugar Cane, meat , and dairy products. glycine also has a hydrogen side chain which is absent in other amino acids.
Hence we can conclude that To make glycine ( amino acid ) from glucose ; Oxygen, carbon or hydrogen is needed and they come from the consumption of Protein-rich food and from respiration.

Which statement about the relationship between the ocean and the rest of Earth's water is true
A. The ocean is connected to all of Earth's freshwater through evaporation and precipitation.
B. The ocean is connected to all of Earth's freshwater through circulation.
C. Freshwater sources are connected to each other through evaporation and precipitation.
D. Ocean waters are connected to each other through circulation. Salt water and freshwater are not linked in any way
please help me asap
Answer:
Choice A
Explanation:
The water cycle connects all types of water, since the clouds of sea water or fresh water are moved then become rain somewhere else.
The statement about the relationship between the ocean and the rest of Earth's water is true, is the ocean is connected to all of Earth's freshwater through evaporation and precipitation. The correct option is A.
What is the ocean?About 71 percent of the surface of the Earth is covered by the ocean, a vast body of saltwater. The abundance of water on Earth is truly exceptional.
Water helps link the Earth's lands, oceans, and atmosphere into a cohesive system, which is essential to sustaining life.
The oceans not only contribute evaporated water to the water cycle, but they also permit water to travel throughout the world as ocean currents. Oceans serve as nature's reservoirs for water, which it uses to power the water cycle.
Therefore, the correct option is A. The ocean is connected to all of Earth's freshwater through evaporation and precipitation.

What is gel electrophoresis? Explain how the length of base pairs flow through the gel.
Answer:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size.

List the layers of the Earth in order from least dense to most dense.
Answer:
Crust, mantle, outer core, and inner core
Explanation:
inner Core-A-Solid&4300-6700°C-Most Dense Outer Core-B-Liquid& 3700-4300°C Mantle-C-Plastic& 1000-3700°C Crust-D-Rocky & 0-1000°C-Least Dense SG # 12 & 15
The layers of the Earth from the most dense to the least dense are:
Inner CoreOuter CoreLower MantleUpper MantleCrustDensity is how much mass an object has for each unit of volume. This just means how much space something takes up compared to the amount of matter that it has. When something has a lot of mass compressed into a comparatively small space, we can say that object has a high density or that it is very dense.
The Core of the Earth is divided into an inner core which is the densest, and a slightly less dense outer core. Both of these are made of iron, nickel, sulfur, and oxygen. The mantle is also divided into two parts, an Upper and a much thicker Lower Mantle. The Lower mantle is denser than the upper mantle. These layers are made of silicate rock. The most superficial and least dense layer of the Earth is the Crust.
Therefore the layers of the Earth from most to least dense are the Inner Core, Outer Core, Lower Mantle, Upper Mantle, and Crust.

Answer: Haiti is mainly know for their minerals! the main minerals extracted are: cooper, silver, and GOLD. Haiti has many many gold farms, markets, etc. HOWEVER this is a very poor area, as people here live off of only about 2 dollars per day. They could take this wealth and put it towards the people, roads, and construction, as they had an earthquake that killed many many people, and destroyed much. If you mean what they do with gold, they take the gold from farms, and mine it underground. They then sell it for money as this is a poor area as said before!
