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.

The picture shows a Single-celled organism that has a nucleus and organelles, lacks a cell wall, and obtains food by eating other organisms. The organism also has cilia that it uses to move through water. Which kingdom should this organism be classified?
Science
Protista
Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be. They are small, although many are big enough to be recognized in a dissecting microscope or even with a magnifying glass. Nutrients are acquired by photosynthesis, ingestion of other organisms, or both.
How does having a larger surface area allow more nutrients to enter the cell?
Answer:
Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
Explanation:
Answer:
Due to the larger surface, it allows double the amount of nutirents to enter the cell. The higher the surface area to volume ratio they have, the more effective this process can be.

I really need help!!!!
plzz TUTUT
Answer:
give me brainlest
Explanation:
Causes
To understand diabetes, first you must understand how glucose is normally processed in the body.
How insulin works
Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas).
The pancreas secretes insulin into the bloodstream.
The insulin circulates, enabling sugar to enter your cells.
Insulin lowers the amount of sugar in your bloodstream.
As your blood sugar level drops, so does the secretion of insulin from your pancreas.
The role of glucose
Glucose — a sugar — is a source of energy for the cells that make up muscles and other tissues.
Glucose comes from two major sources: food and your liver.
Sugar is absorbed into the bloodstream, where it enters cells with the help of insulin.
Your liver stores and makes glucose.
When your glucose levels are low, such as when you haven't eaten in a while, the liver breaks down stored glycogen into glucose to keep your glucose level within a normal range.
Causes of type 1 diabetes
The exact cause of type 1 diabetes is unknown. What is known is that your immune system — which normally fights harmful bacteria or viruses — attacks and destroys your insulin-producing cells in the pancreas. This leaves you with little or no insulin. Instead of being transported into your cells, sugar builds up in your bloodstream.
Type 1 is thought to be caused by a combination of genetic susceptibility and environmental factors, though exactly what those factors are is still unclear. Weight is not believed to be a factor in type 1 diabetes.
Causes of prediabetes and type 2 diabetes
In prediabetes — which can lead to type 2 diabetes — and in type 2 diabetes, your cells become resistant to the action of insulin, and your pancreas is unable to make enough insulin to overcome this resistance. Instead of moving into your cells where it's needed for energy, sugar builds up in your bloodstream.
Exactly why this happens is uncertain, although it's believed that genetic and environmental factors play a role in the development of type 2 diabetes too. Being overweight is strongly linked to the development of type 2 diabetes, but not everyone with type 2 is overweight.
Causes of gestational diabetes
During pregnancy, the placenta produces hormones to sustain your pregnancy. These hormones make your cells more resistant to insulin.
Normally, your pancreas responds by producing enough extra insulin to overcome this resistance. But sometimes your pancreas can't keep up. When this happens, too little glucose gets into your cells and too much stays in your blood, resulting in gestational diabetes.

The test: To understand if the ACTN3 protein affects running ability, researchers conducted a test. They recruited a group of competitive runners and measured the level of ACTN3 protein molecules each runner had in their bodies. Then, they had the runners participate in a sprint (a short-distance run). During the test, the runners sprinted as fast as they could for 100 meters.
Evidence: Scientists found that the runners who sprinted the fastest had the highest amount of ACTN3 protein molecules in their bodies.
Do you think that this evidence shows that the ACTN3 protein determines running ability? Explain your ideas using the words protein, trait, and feature in your response.
Answer:
The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers. ... Although having one or two variant forms of the ACTN3 gene does not have any harmful effect, an individual's ACTN3 genotype does affect their athletic ability.

However if the organism is killed by a predator, the predator will then receive their share of energy by eating the organism.
A mother and father have two daughters. The daughters have some similar and some different physical features. Which statement best explains why the daughters’ physical appearance includes both similar and different features?
A: One daughter received fewer genes than the other.
B: Each daughter received a different number of genes from each parent.
C: The daughters received a random set of genes from both of their parents.
D: One daughter received all her genes from her father, and the other daughter received all her genes from her mother
C: The daughters received a random set of genes from both of their parents.
The physical appearance of an individual is determined by their genes, which are inherited from their parents. Each parent contributes half of their genes to their offspring, and the combination of genes from both parents determines the physical characteristics of the offspring.
When the two daughters inherit genes from both their parents, they receive a random set of genes from each parent, which can result in both similar and different physical features. Therefore, statement C is the best explanation for why the daughters' physical appearance includes both similar and different features.
