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

Explanation:
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
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.

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?
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.

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
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

Answer:
Dire wolves- these wolves had long ulna and radius bones to support the wolve's need to run for extended periods of time to hunt animals. The distal bones allowed the wolves to keep the wolf balanced and helped ensure the body could handle running on land
the fruit bat- the small yet long and thin ulna, radius, and distal bones of the fruit bat ensure the bat is light enough to fly quickly and avoid weighing down the bats wings. the light bones allow the bat to fly quickly as the bats do not require strong bones to run like the dire wolf
