Could the blue jays ever have had thin beaks? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)
1. No blue jays could have been born with a thin-beak trait because none of the adult blue jays had that trait to pass down.
2. No blue jays could have been born with a thin-beak trait in the past, but some with that trait could be born in the future if the environment changes to have pine cones with seeds.
3. A blue jay could have been born with a mutation in its genes for the thin-beak trait and lived for a little while, but it would have been more likely to die before it had offspring.
4. A blue jay could have been born with a mutation in its genes for the thin-beak trait, but having a mutation in its genes would have caused it to die when it was born.
Answers
Answer:
i believe the answer is 2)
Explanation:
because birds that eat seeds need to have thinner beaks in order to get to the seed. seeing as how their beaks are currently too large for that, they wouldn't be able to reach the seeds- they would have to adapt to the new environment **if that were to happen**
good luck :)

Do large muscles occur naturally in some other living things? (List the living things and explain why you think these larger muscles occur naturally.)
Answers
Answer:
Yes, large muscles occur in some other living things. I think this because lets say you have a cheetah. Well, that cheetah runs very fast AND uses muscular endurances to hunt and chase its prey down. So yes, they start to devolp some large muscles. Some other living things that might have large muscles could be a bear, rhino, lion, tiger, or even a dog. As you can see, its more so the larger animals that devolp these large muscles.

Which of the following pieces of evidence supports the theory of plate tectonics?
A
the size and shape of Earth
B
the composition of Earth's layers
C
tectonic plates observed from satellite images
D
similar mountain ranges found on different continents
Answers
Similar mountain ranges found on different continents supports the theory of plate tectonics. Therefore, option (D) is correct.
What is the plate tectonic theory?Plate tectonics is a scientific theory that attempts to explain the formation of significant landforms on Earth as a result of the movement of the Earth's tectonic plates.
Where two continental plates clash, mountains are created. Due to their identical weight and thickness, neither plate will bury beneath the other. Instead, they fold and collapse, pushing the rocks upward to create a mountain range. Mountains will continue to rise in height as the plates continue to collide.

Which of these steps would help to reduce the chances of a mudslide occurring in a hilly region?
A
leaving the trees and other plant cover on the hillsides
B
removing all trees and plant cover from the hillsides
C
building fences at the bases of the hills
Answers
Answer:
Option A. Leaving the trees and other plant cover on the hillsides.
Explanation:
Mudslide: When a bulk of soil slides down a steep hill or mountain causing damage to the flora and fauna of the place.Mudslide leads to soil erosion in hilly areas.There are various causes of mudslide such as:Heavy rainfall that pushes the soil/mud down the hill.Gushing water or accumulated water absorbed by the soil reduces fiction and causes mudslide.Earthquake can also lead to mudslide as it shakes the ground and starts the downward movement of soil.Mudslide harms the trees, plants, vegetation, blocking roads, railway tracks, etc.One of the ways of prevention from mudslides is planting trees and grasses on steep hills. The roots of the plants and trees could grip and hold the soil together which could protect the soil from easily falling down the hill.For more information:

In a few words, describe the differences in a recessive phenotype and a dominant genotype.
Answers
Answer:
Recessive phenotype is that type of phenotype that is expressed by an organism only when both the alleles of a genotype are recessive. Dominant genotype is that type genotype were either one of the alleles or both the alleles are dominant.
Explanation:
Phenotype is the physical appearance of an organism whereas genotype is the genetic makeup of an organism. A recessive phenotype is expressed only when both the alleles are recessive for the trait.
What is genotype and phenotype?
The genotype of an individual is their unique sequence of DNA or genome. More specifically, the term genotype is used to refer to the two alleles a person has inherited for a particular gene from their parents. Phenotype is the physical appearance or expression of the genotype.
Recessive phenotype is the type of phenotype which is expressed by an organism only when both the alleles of a gene are recessive in that organism. And, dominant genotype is the type of genotype which is observed when either one of the alleles or both the alleles are dominant for that trait.

Explanation: If the water outside the cell has LESS water than inside, water will move from the inside of the cell to the outside. That is what happened to the Gummy Bear in the salt. The water had to move out of the Gummy Bear to “even out” the concentration of water. The Gummy Bear became smaller with less water to fill it up. So why didn’t the Gummy Bear in salt water get as big as the Gummy Bear in plain water? Since there was sugar in the water AND in the Gummy Bear, the water didn’t have to move as much to “even out” the concentration.

The image shows an example of an external environment affecting her fish's growth. Other conditions that could affect animal growth include internal environment.
What is environment?An organism's or an ecological community's environment is the collection of physical, chemical, and biological variables that affect it and ultimately decide its form and survival.
Everything in our environment affects us. Whether they are living or not is up to you. It consists of natural forces such as chemical and physical ones.
Environments are where living things exist. They are continually interacting with it and modifying their behavior to fit the circumstances.
Clean air and water, rich land for growing food, as well as energy and material inputs for production, are all provided by good natural surroundings.
The picture demonstrates how an outside environment can effect a fish's growth. Internal environment is another factor that might influence an animal's growth.
Thus, this can be the complete scenario for the gold fish.

The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.
Answers
Answer:
Since the alligator population decreased, this means there are less predators for the gar. Less predators for the gar mean the gar population will increase. More gar means more predators for the crabs, and therefore decrease the crab population. More gar also means more competition for the diving duck in terms of animals that eat crabs, and thus the diving duck population will also decrease.
Explanation:
To fully understand this question it is important to realize the relationship in this food web. It is important to note that the alligators will eat gar, the gar will eat crab, and the diving duck also eat carb. If the predator population decreases, then the amount of prey will be able to increase since there are less predators hunting them. If the predator population were to increase, there would be less prey, since more predators are hunting them.
The data showed the decrease in the population of alligator. The decrease in the population of alligator will increase the population of gar and, which will decrease the population of crabs, and it increases the competition between gar and diving duck.
What is the relationship between different animals?All animals and plants are dependent on each other. In the given picture, the crabs, crocodiles, gar, and diving duck is given.
If there will be fewer crocodiles, the population of gar will increase that affects the population of crabs, because duck and gar both will eat the crabs.
Thus, the decrease in the population of alligator will increase the population of gar and, which will decrease the population of crabs, and it increases the competition between gar and diving duck.

C. Cells are living and the organelles that make them up are nonliving.
D. Cells are nonliving and the organelles that make them up are also nonliving.
Answers
Answer:
I love science here's a explanation of all of your choices
Explanation:
An organelle (think of it as a cell's internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.
A Therefore, cells not only make up living things; they are living things. Cells are found in all plants, animals, and bacteria. Many of the basic structures found inside all types of cells, as well as the way those structures work, fundamentally are very similar, so the cell is said to be the fundamental unit of life.
B The key principle is that the smallest unit of life is the cell. ... But anything that makes up a cell necessarily has to not be alive. So all of the organelles in a cell like the nucleus, mitochondria, and endoplasmic reticulum are all non-living
C A non-living thing is not organized into cell(s); a living thing is. Although both non-living and living things are essentially made up of molecules of elements and compounds, a living thing would be made up of biomolecules organized into structures of a cell.
D All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms. (This requirement is why viruses are not considered living: they are not made of cells. ... Cells are classified as prokaryotic or eukaryotic.

The deadliest U.S. hurricane on record was a Category 4 storm that hit the island city of Galveston, Texas, on Sept. 8, 1900. Some 8,000 people lost their lives when the island was destroyed by 15-ft waves and 130-mph winds.[2]
Over 1/3 of cat and dog owners don't have a disaster preparedness plan in place for their animals. Help neighbors and friends come up with a hurricane plan for their pets. Sign up for Save Our Pets.[3]
In the Atlantic, hurricane season starts June 1, while in the Pacific it starts May 15. Both end on November 30.[4]
When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge.[5]
40% of the hurricanes that occur in the United States hit Florida.[6]
The difference between a tropical storm and a hurricane is wind speed – tropical storms usually bring winds of 36 to 47 mph, whereas hurricane wind speeds are at least 74 mph.[7]
Hurricanes rotate in a counter-clockwise direction around the eye. The rotating storm clouds create the "eye wall," which is the most destructive part of the storm.[8]
Hurricanes are classified into 5 categories, based on their wind speeds and potential to cause damage. Names can be "retired" if a hurricane has been really big and destructive. Retired names include Katrina, Andrew, Mitch and most recently Sandy.[9]
When the National Hurricane Center began giving official names to storms in 1953, they were all female. This practice of using only women’s names ended in 1978.[10]
The costliest hurricane to make landfall was Hurricane Katrina, a Category 5 storm that slammed Louisiana in August of 2005. Damages cost an estimated $108 billion.[11]

What do you mean by predators?A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism.
Predation involves four steps: search, recognition, capture, and handling. The possibility of co-evolution of predator and prey operates at each of these steps. Predators search the environment for acceptable prey.
