If cells from one part of an embryo are transplanted to another part, and they develop into the tissue they would have made originally, the cells are said to be ____________ .
Answer:
determined
Explanation:
Determined cells are embryonic cells that will generate all the cell types of the adult organism, with this process being independent of environmental inputs. Cell determination is defined by specific gene expression patterns in embryonic cells. In consequence, cell determination is defined as a genetic process where a particular cell fate can be broken down into two different states: specified (committed) or determined. If a cell is in a committed/specified state, the cell's fate can still be reversed or transformed, while if a cell in a determined state, the cell's fate cannot be reversed or transformed.

which process in photosynthesis uses energy from the sun
Answer:
splitting water into hydrogen and oxygen
Explanation:
because
The light-dependent reaction
The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine. The light waves' energy is captured by the chlorophyll and transformed into chemical energy in the form of the molecules ATP and NADPH.
What is Photosynthesis ?
Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. Despite the fact that various species undertake photosynthesis in different ways, the process always starts when proteins called reaction centres that contain green chlorophyll absorb energy from light. Unlike bacteria, which have these proteins incorporated in the plasma membrane, plants store these proteins in organelles called chloroplasts, which are most prevalent in leaf cells.
When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones. Animals use ATP to retain the energy released during meal digestion. Similar to this, plants use ATP molecules to store the energy they obtain from light during photosynthesis.
In addition to converting ADP to ATP, photosynthetic processes are used by plants to absorb, process, and store solar energy. Animals convert ADP to ATP, which can subsequently be utilised to drive essential development and cell maintenance, using the energy supplied from the breakdown of glucose and other molecules.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result.

List and describe the different types of connective tissue. What similarities and differences did you observe?
Answer:
There are three types of connective tissues, loose connective tissues, dense, and hyaline.
Explanation:
The difference between them is the composition of the extracellular matrix that surrounds the fibroblast, that is to say that in loose connective tissue, the function will be of support or filling, and the fibroblast is immersed in an extracellular matrix with a high content of water and proteins. collagen.
On the other hand, in dense connective tissue, the amount of collagen fibers is greater, the protein structure as well, and the interlacing between proteins is more complex, and they may also have the ability to calcify as in the case of bone tissue or cartilage.
Finally, we have the hyaline connective tissue, which is very rich in hyaluronic acid and is found in the joints forming the discs, which are shock absorbers and protectors from bone wear due to friction between surfaces, hyaluronic acid, proteinglycans and glycoproteins are the main protagonists of all connective tissues together with the fibroblast, but even more so in the hyaline connective.

It allowed us to put a formation date on some geologic crosections
It allowed us to disprove the existence of land bridges
It allowed us to start using the idea of superposition
Answer:
It allowed us to put a formation date on some geologic crossections
Explanation:
Absolute dating is a newer way of evaluating the chronology of historical events by assigning numerical ages to them. The age thus assigned might not be the exact age but it is still closer to the real age.
It is unlike relative dating techniques which simply give the chronology or order of past events instead of the exact dates. Relative dating techniques have been in use before the emergence of absolute dating techniques in the twentieth century.

What was the result of using drainage blocks to keep water in the field level during the growing season?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).
High tide is occurring on the sides of the Earth that are_______.
A. -experiencing sunrise and sunset.
B. -closest to and farthest from the Sun.
C. -halfway between the Sun and the Moon.
D. -closest to and farthest from the Moon.
High tide is occurring on the sides of the Earth that are closest to and farthest from the Moon. The correct option is D.
What is high tide?When the sea or a river reaches its greatest level and moves the farthest up the beach or the bank, it is said to be at high tide.
The gravitational forces that try to pull the water away from the moon are resisted by the water that is travelling away from the moon.
On the far side of the Earth, where the moon's gravitational pull is weaker, inertia triumphs, the ocean swells, and high tide happens.
The rise and fall of the sea's surface on a regular basis is what tides, which start in the oceans, appear as as they move toward the coastlines.
High tide is when the wave's highest portion, or crest, reaches a specific area; low tide is when the wave's lowest portion, or trough, happens.
Thus, the correct option is D.

how did the settlers view panther when they came to north America
Answer:
They viewed the Panther with fear and set out on a mission to exterminate it.
Explanation:
The first Spanish conquistador to ever sight a Panther was Alvar Nunez Cabeza de Vaca in 1513. When he saw the panther which he referred to as a lion, he was fearful of the animal. He and other Europeans set out on a mission to exterminate all Panthers. This was also necessary as they had to clear the bushes for them to reside.
In 1821 when Florida officially became a part of the United States, and people had to relocate there, a $5 dollar bounty was placed on every Panther killed. The Panthers relocated farther into the wild. As of 1990, the population of the Panther was just around 50. Panthers have since been named an endangered species.
