How can there be so many similarities between organisms, but also so many different types of plants, animals,
and microorganisms?
Answer:
Many of the similarities between organisms are the result of inheritance: organisms inherit features from their ancestors which they often use in similar ways. ... Other similarities occur because organisms at all places and times face similar problems: finding mates, avoiding predators, obtaining food.

Answer:
not all organisams are diffrent,just know that.

which of these are claims of pseudoscience most likely based on?
A. Critical Thinking
B. Logical Reasoning
C. Controlled Experiments
D. Creative Imagination
Answer: I think the answer is creative imagination
Explanation:
The definition of pseudoscience is:
a collection of beliefs or practices mistakenly regarded as being based on scientific method.
Here is something I found online
A pseudoscience is a fake science that makes claims based on faulty or nonexistent scientific evidence. In most cases, these pseudoscience present claims in a way that makes them seem possible, but with little or no empirical support for these claims. Graphology, numerology, and astrology, are all examples of pseudoscience.
What is the internal and external adaptation in a leaf for photosynthesis? Please give a clear short answer (prefer in bullet points). I will give brainliest to fastest answer
Answer:
They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. ... The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
Answer:
▪︎leaf with large surface area
▪︎dark coloured leaf for maximum sunlight absorbtion
▪︎has stomata openings to allow carbon dioxide diffuse in the leaf
▪︎It has the green pigment :chloroplast inside to absorb sunlight

(select only one answer)
natural selection
Answer:
The correct answer is-
4. true
5. Natural selection
6. microevolution
Explanation:
Adaptive radiation is a cycle where living beings diversifying rapidly from a familial or an ancestral species into a huge number of several new types, especially when there are new environmental aspects present such as different habitats and few competitors.
Thus, it is a true statement.
Natural selection is the cycle through which a population or a species of living beings adjust and change over the period of time. natural selection just acts upon the heritable attributes of a population by choosing for advantageous alleles or and in this manner increasing the frequency of these adaptive alleles in the population.
Thus the option Natural selection is correct.
Changes inside a genetic pool from happening to one generation to another is known as microevolution. Allele frequencies in a population may change because of, natural selection, mutation, genetic drift, and genetic flow.
Thus, the correct answer is - microevolution.

. As the volume of the cell increases, how does the surface area to volume ratio (SA/Ve) change?
Answer: Well, you see, As the cube size increases or the cell gets bigger, then the surface area to volume ratio - SA:V ratio decreases. ... When a cell grows, its volume increases at a greater rate than its surface area, therefore it's SA: V ratio decreases.
Explanation:
How do experiments show cause-and-effect relationships?
Answer:
A cause and effect relationship is when something happens that makes something else happen. ... Cause and effect relationships are also found in stories. For example, if Mae is late to school, she might lose recess time. In that case, being late to school is the cause and the effect, or result, is her losing recess time.

A science class investigated the relationship between the amount of time
students spend doing chores every night and their average grades on
schoolwork. Which statement from the lab report best represents a
conclusion?
A. Based on our results, students who do 1 hour of chores per night
have grades that are on average 0.2 points higher than students
who do no chores.
B. Doing chores at night actually helps students do better at school,
even if it seems like the opposite would be true.
C. We believe that students should spend at least 2 hours doing
chores every night if they want to get better grades at school and
help their families.
OD. If students spend at least 1 hour per night on chores, then they are
guaranteed to get higher grades on their schoolwork.
Answer:
A. Based on our results, students who do 1 hour of chores per night
have grades that are on average 0.2 points higher than students
who do no chores.
Explanation:
In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.
From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.
The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.

The forebrain is composed of the cerebrum (telencephalon), thalamus, hypothalamus, pineal gland and limbic system.
The cerebrum is recognized to be the biggest portion of the brain.
On the other hand, the cerebellum is a brain structure located between the brainstem and the cerebrum.
The functions of the cerebellum include motor abilities, sensory perception and body posture/balance.

Whole brain death occurs when the ______ ceases to function.
Answer:
Whole brain death occurs when the BRAINSTEM ceases to function.
Explanation:
In the US, whole brain death = legal death. Most people consider that a person is brain dead when the cerebrum, or the higher brain, is dead because the person is not able to think or have control over his/her body, but legally you are brain dead only when the brainstem ceases to function. The brainstem is responsible for keeping you alive and performing the most basic bodily functions like breathing and keeping your heart beating. But once it fails, you are legally dead. Even if your body could still survive using a ventilator and other devices, your brain has ceased to work and you wouldn't be able to survive if you were unplugged.

How many grams of solute are needed to make 250 mL of a 2.055 M NaCl solution?
30 grams
76.7 grams
300.081 grams
58.44 grams
Answer:
30grams
Explanation:
To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;
M = n÷ V
Where; M= Molarity or Molar concentration = 2.055M
n= number of moles= ?
V= Volume = 250mL
Volume in L is 250/1000 = 0.250L
n= M × V
n= 2.055 × 0.250
n= 0.51375moles
The mass is calculated using :
Mole (n) = mass (m) / molar mass (MM)
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mass = molar mass × mole
Mass = 58.5 × 0.51375
Mass = 30.0543
Therefore, the mass is 30grams
