Plants have what is called an blank life cycle
Answer:
Haploid and diploid life cycle. Haploid male and female cells form together to create a diploid zygote, however when spores or seeds are released (depending on the type of plant) these are once again haploid cells - hence the cycling between cell states
Animals like sea turtles and dolphins would be found in the neritic zone.
T or F
Answer:
T ~ True
Explanation:
The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor. Due to the abundant supply of sunlight and nutrients in this zone, it is the most productive ocean zone supporting the vast majority of marine life. As a result, many organisms that require light for photosynthesis can live in this zone, including seaweeds and phytoplankton. Most coral reefs are also found in the neritic zone. ... Swimming organisms in the pelagic zone include dolphins, whales, squid, and numerous species of fish adapted to life at different depths.

would it be ideal if temperatures are often below freezing where you launch rockets?
Explanation:
And it should go without saying that you don't want to launch during a hurricane or tornado. If the rocket flies into a thunderstorm then it will attract lightning strikes. This was partly attributed to the low temperature weather, far lower than had been the case with previous launches: below freezing at 28.

Sydney and Valparaiso are the same distance from the equator and both are near the ocean. Is Valparaiso warmer, colder, or the same temperature as Sydney?
Answer:
They are the same in temperature both of Valparaiso and Sydney because they have equal distance from the equator and the same geographical location which gives sense that they are similar in weather patterns and climate but depends on phenomenal events.
Explanation:
The Equator is the imaginary middle latitude, which divides the Earth into Northern and Southern hemispheres.
Sydney and Valaparasio are equidistant from the equator and have the same climatic conditions.
Sydney is located 2,340 miles away from the equator. The city is located near the ocean and enjoys a sunny climate with warm summers and little winters. The average temperature ranges between 18.6-degree to 25.8-degree Celcius.
Valparaiso is situated 2,284 miles away from the equator and near the ocean. The city enjoys mild winters, humidity, and comfortable summers. The average temperature of the city ranges between 14-degrees to 30-degrees.
However, the other phenomenal events can cause a change in the climatic conditions of a city.

Explain how plates move at a convergent plate boundary.
(Plz make it simple)
Answer:
At convergent plate boundaries, oceanic crust is forced down into the mantle where it begins to melt. Magma rises in and out the other plate and solidifies into granitewhich is the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Svetlana learned that there are organisms that live deep in the ocean that produce food using energy stored in chemicals.
What process do these organisms most likely use to produce food?
Answer:
chemosynthesis
Explanation:
the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
There are two various ways by which organisms produce food. This is through photosynthesis which is utilized by plants and chemosynthesis which is utilized by some other organisms.
The process by which organisms that live deep in the ocean produce food using energy stored in chemicals is through chemosynthesis.
Organisms that live deep in the ocean are unable to access sunlight to enable them produce their food so they use the process of chemosynthesis.Chemosynthesis is utilized by some bacteria. They do this by using chemicals in the place of sunlight unlike photosynthesis as a source of energy to produce food (glucose). It involves the conversion of one or more carbon-containing molecules (e.g methane) into organic matter using the oxidation of inorganic chemicals.Learn more: https://brainly.com/question/15115717

10. A) Based on the information in the article, what kind of changes have taken place in the red blood cells of a person with sickle-cell anemia? (Give at least two changes.) (2 points)
Answer:
Explanation:
The shape of the blood cell is sickle unlike the red blood cell that is oval or ameoboid this shape allows for the low intake of oxygenated blood that is needed in the body.
Sickle blood does not last long in the blood system it takes just about 10days while the red blood cell last about 165 days in the system there a sickle cell individual blood must be regenerated and recycled in about every 10days
Mutation in the blood cell is the major challenge of an individual with sickle cell anaemia.
A cell membrane is more flexible than a brick wall. Why might many cells benefit from a flexible cell membrane? and A building has different types of openings, such as windows and doors. Do you think a cell also has different types of openings? Give an explanation for your answer. I NEED HELP NOW I HAVE TO SUBMIT
Answer:
plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.
Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.
A cell membrane's flexibility aids in the selective passage of substances across it. Endocytosis, a mechanism that enables amoeba to take in food particles from the environment, is made possible by the flexibility of the membrane.
What make cell membrane to be flexible?The majority of natural phospholipids' fatty acids include one or more double bonds, which cause the hydrocarbon chains to twist and are challenging to pack together.
The interior of the membrane can displace freely due to the prolonged hydrocarbon chains of the fatty acids, getting the membrane itself negotiable and supple.
Key fatty acids include arachidonic and docosahexaenoic acids. Due to its four double bonds, arachidonic acid's proportion in phospholipid tails can be slightly increased to improve membrane flexibility.
Therefore, cell flexibility is important for cell to function.

What alternate form of genes do nucleic acids have that allows them to offer variability? allele codon nucleotide chromosome
Answer:A-Allele
Explanation:
just took the quiz
The alternate form of gene that nucleic acids have that allows them to offer variability is the allele that is present in the first option, and there are more than two alleles present for one gene.
What is the gene?The gene is the message that is present in the DNA, and the gene of the prokaryotes contains very few introns, while the gene of the eukaryotes contains many introns, and the genes only express their exon parts, not the introns. In most cases, the gene has two alleles, and depending on the alleles' presence on the homologous chromosomes, the character is expressed. Some genes that have more than two alleles are called multiallelic genes, and they show the combined effects of their alleles.
Hence, the alternate form of gene that nucleic acids have that allows them to offer variability is the allele that is present in the first option.

two tectonic plates. What type of boundary is represented in the diagram?
a)subduction
b)convergent
c)divergent
d)transform
Answer:
D
Explanation:
The arrows on either side of the fault represent the relative movement of the two tectonic plates. The type of boundary is represented in the diagram is convergent. Thus, option B is correct.
What is tectonic plates?
Earth’s tectonic plates are part of the planet’s crust which correctly describes Earth’s tectonic plates. Huge fragments of the upper mantle and crust make form tectonic plates. Both continental and oceanic crust make up their composition. Mid-ocean ridges and the significant faults that delineate the plate boundaries are subject to earthquake activity.
Our globe would look drastically different if it weren't for plate tectonics. We have a stable climate, mineral and oil deposits, and oceans with a chemical balance that supports life thanks to the continuous recycling of the Earth's crust.
The tectonic plates, which have a thickness of about 100 km, are made up of this crustal layer of the globe. These plates, which continue to float on the warm and thick mantle, collided to create the mountains.
Therefore, The arrows on either side of the fault represent the relative movement of the two tectonic plates. The type of boundary is represented in the diagram is convergent. Thus, option B is correct.
