How are dinosaurs are like ( Related) crocs
How are dinosaurs like( related) chickens
Answer (How dinosaurs are related to crocodiles):
Along with pterosaurs and dinosaurs, crocodiles were an offshoot of the archosaurs, the "ruling lizards" of the early to middle Triassic period; needless to say, the earliest dinosaurs and the earliest crocodiles resembled one another a lot more than either resembled the first pterosaurs, which also evolved from archosaurs. What distinguished the first crocodiles from the first dinosaurs was the shape and musculature of their jaws, which tended to be much more deadly, as well as their relatively splayed limbs—as opposed to the straight, "locked-in" legs of theropod dinosaurs. It was only well into the Mesozoic Era that crocodiles evolved the three main traits with which they're associated today: stubby legs, sleek, armored bodies, and marine lifestyles.
Answer (how dinosaurs are related to chickens):
The scientific evidence comes from a study in which the amino-acid sequence from T. Rex collagen was compared to that of various modern species. It proved to be more similar to the chicken than any other creature alive today.
So, are chickens dinosaurs? No – the birds are a distinct group of animals, but they descend from the dinosaurs, and it’s not too much of a twist of facts to call them modern dinosaurs.
There are many similarities between the two types of animal, largely to do with bone structure. It also appears that many of the dinosaurs had feathers – not for flight, but as adapted scales, to assist in heat regulation, and/or to assist in courtship displays, as in modern birds.

In a pedigree, an affected male would be designated by:.
Answer:
a shaded square
Explanation:
trust me bro
In a pedigree, an affected male would be designated by a shaded square. The correct answer is option 3.
A pedigree is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors from one generation to the next.
In a pedigree, an affected male would be designated by a shaded square. This is because squares represent males in a pedigree, and shading indicates that the individual is affected by the trait being studied. In contrast, an open square would represent an unaffected male. Similarly, a shaded circle would represent an affected female, while an open circle would represent an unaffected female.
Therefore, a pedigree would show a shaded square for an affected man. Option 3 is the right answer.

Why is ocean acidification important to us?
What will happen to the pH of the water when CO2 is added?
What does the abbreviation “pH” stand for?( briefly explain)
#1
Ocean acidification is harmful for aquatic ecosystemThis is being reason for death of many aquatic creatures#2
CO_2 will form carbonic acid which is acidic in nature
So it will decrease the pH#3
PH stands for potential of Hydrogen .
If pH is less than 7 it's acidic and if greater than 7 it's basicExplanation:
Acidification reduces the availability of carbonate ions in ocean water, which provide the building blocks these organisms need to make their shells and skeletons, significantly reducing the chances for their offspring to survive.
when carbon dioxide is dissolved in water, the release of hydrogen ions in carbonic acid is what lowers the pH. As CO2 levels increase around Earth, the amount of dissolved CO2 also increases, which increases the amount of carbonic acid, therefore decreasing the pH.
pH stands for "power of hydrogen." The "H" is capitalized because it is the hydrogen element symbol. pH is a measure of how acidic or basic an aqueous solution is. It is calculated as the negative logarithm of hydrogen ion concentration.

Plants, like animals and other organisms, must adapt to their changing environments. While animals are able to relocate from one place to another when environmental conditions become unfavorable, plants are unable to do the same. Plants must deal with changes in their environment in a different way. Plant tropisms are mechanisms plants use to respond to their environment. A tropism is a growth toward or away from a stimulus. Common stimuli that influence plant growth include light, gravity, water, and touch. Evaluate each of the tropisms. Select ALL of the choices that correctly pairs the type of tropism with its environmental stimulus.
A) phototropism: growth toward light
B) hydrotropism: growth in response to water
C) thigmotropism: growth in response to touch
D) geotropism: growth in response to soil conditions
E) thermotropism: growth in response to temperature
Answer:
A,B,C, and D
Explanation:
Forms of tropism include phototropism (response to light), geotropism(response to gravity), chemotropism (response to particular substances), hydrotropism (response to water), thigmotropism (response to mechanical stimulation), traumatotropism (response to wound lesion), and galvanotropism, or electrotropism (response to electric current).
