How can the amount of energy absorbed by Earth's surface change?

Answers

The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface.

katelyn is working on a project about classifying cells as either prokaryotic or eukaryotic. she is observing a cell under an electron microscope that does not have a cell wall but does have a nucleus. how should katelyn classify this cell? A. as a prokaryotic cell B. as a eukaryotic cell C. there is not enough info to classify this cell D. the cell had components of both types

Answers

I would say B. an eukaryotic cell!

A eukaryote can be a plant or animal cell. They have a nucleus and animal cells do not have a cell wall. So specifically probably an animal cell but for this question an eukaryotic cell is the answer!

A prokaryotic cell lacks a nucleus but do have a cell wall but this can’t be the answer because of the lack of a nucleus.

So B! Eukaryotic cell! Hope this helped!

Katelyn should classify this cell as a eukaryotic cell. The presence of a nucleus is a defining characteristic of eukaryotic cells, while prokaryotic cells do not have a nucleus. The absence of a cell wall is not enough to classify a cell as prokaryotic, as some eukaryotic cells also lack cell walls.

What are eukaryotic cells?

Eukaryotic cells are cells that have a distinct membrane-bound nucleus and other membrane-bound organelles that carry out specific functions. These cells are typically larger and more complex than prokaryotic cells, which lack a nucleus and organelles.

Eukaryotic cells are found in plants, animals, fungi, and protists. They are characterized by their compartmentalization, meaning that various parts of the cell are separated by membranes, allowing for specialized functions to be carried out within specific areas of the cell.

Examples of eukaryotic organelles include the mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes.

What could you make or do to make sure your bean plants stay upright and don’t fall down?

Answers

Answer:

I got this off of g o o g l e

Explanation:

I put pairs of small fence posts (one on each side) down the row. I then tied twine to the fence post and ran it on either side of the plants. This keeps them from falling over to the side. If you plant thick enough they won't fall to the front or back.

Seedlings fail to emerge. Several possible causes: (1) Beans are a warm weather crop and seed may rot in soil less than 50° to 60° F. Delay planting until the soil has warmed; (2) Soil is heavy or crusted; seedlings may not be able to push through. Add aged compost to the planting bed; cover seed with light compost mulch; (3) Seed was sown too deep or not deep enough. Beans planted in spring 2 inches deep or more may rot and fail to germinate. Beans planted at the end of spring or in summer may dry out and die if sown less than 1 inch deep. Plant beans about 1 inch deep in early spring; 2 inches deep later in the season

Where are fats, carbohydrates, and proteins broken down into particles small enough to be absorbed into the body?
Hint: These enzyme-rich juices break the fat molecules down into fatty acids
and glycerol for easier absorption into the body.
The enzymes also carry out the final deconstruction
of proteins into amino acids
and carbohydrates into glucose.
This happens in the small intestine's lower regions,
the jejunum and ileum,
which are coated in millions of tiny projections called villi.

Options:in the stomach
in the illium
in the duodenum
in the jejunum

Answers

Answer:

Duodenum (option 3)

Explanation:

Digestion of carbohydrates, proteins, and fats continues in the small intestine. Starch and glycogen are broken down into maltose by small intestine enzymes. Proteases are enzymes secreted by the pancreas that continue the breakdown of protein into small peptide fragments and amino acids.

The duodenum is the first section of the small intestine and is the shortest part of the small intestine. It is where most chemical digestion using enzymes takes place

This happens in the pancreas

Komodo dragons (a lizard species) and red-tailed boas (a snake species) are both reptiles. They share a common ancestor population that lived about 250 million years ago, but they have been separated in different environments, with different food sources, for millions of years. Komodo dragons and red-tailed boas have some shared structures. They also have some differences in their structures.

1.Why do Komodo dragons and red-tailed boas have some shared structures and some different structures?

Answers

They have similar characteristics and structures because they are both reptiles and came from a common ancestor. That meant that, going back in time, both of these creatures were once one common, ancestral animal. Once the animals were put into different environments, they changed and evolved overtime in order to adapt to the challenges in the habitat specific to them. But, because they come from a common ancestor, they started from the same ‘base’, and will still share similarities today.

Komodo dragons and red-tailed boas have some shared structures because they both evolved from a common ancestor population that lived about 250 million years ago.

What is the difference has come over the time in these species?

Over time, as these two species separated into different environments with different food sources, they underwent separate evolutionary trajectories that led to differences in their structures. However, many of the underlying genetic and developmental mechanisms that produced their ancestral structures are still present in both species.

For example, both Komodo dragons and red-tailed boas have scales, which are a common feature of reptiles. Scales serve to protect the skin from abrasion and injury, as well as to reduce water loss. They also both have a vertebral column, which provides support for the body and protects the spinal cord.

At the same time, Komodo dragons and red-tailed boas have differences in their structures because they evolved in different environments and have different feeding strategies. Komodo dragons are large, carnivorous lizards that use their sharp teeth and powerful jaws to hunt and kill prey, while red-tailed boas are constrictor snakes that use their muscular bodies to suffocate and swallow their prey whole.

As a result, the structures of their jaws, teeth, and digestive systems are adapted to their respective diets and hunting strategies, and differ in significant ways.

Overall, the shared and different structures between Komodo dragons and red-tailed boas reflect both their common evolutionary heritage and their divergent evolutionary trajectories.

Answer:

Estrogen and Progestrone harmone help in the thickening of the inner wall of the uterus i.e. endometrium layer,for the reception of fertilized eggs and their development.

Progestrone prepares the uterus for a fertilizef egg to implant.

The uterus lining sheds if no fertilization occured because the sperm passes through the uterus so.the lining of the uterus again starts to break down and shed ,and new mestural period begins

Explanation:

Hope this helps u!!

Estrogen :thickens the endometrium,inhibits the action of FSH & LH
Progesterone :thickens the endometrium ,inhibits the action of LSH&LH in the luteal phase and stimulated LH secretion in follicular phase

Uterus lining (endometrium ) thickens during the proliferative phase of the cycle due to progesterone,if there’s no pregnancy the level of progesterone and estrogen decreases (due to breakdown of corpus luteum ) hence resulting into degeneration of the endometrium (Ischemic phase )

At a Convergent boundary continental crust is created and oceanic crust is destroyed and it’s a slow process. At a divergent boundary new crust is generated as the plates pull away from each other and it’s a slow process. At a transform boundary crust is neither produced nor destroyed as the plates slide horizontally past each other and i believe it’s fast.
