It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences
Answer:
Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
Explanation:
Answer:
Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.
During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.
One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.
The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

Differences between the Kutchicetus and the Saber-toothed cat:
The Kutchicetus had a large tail for propelling in the water, and thick blubber to stay warm.
The Saber-toothed cat had a short tail, lived in social groups, and weighed twice as much as the lion.
(They both had proportionally small hind legs compared to the rest of its body.)
Explanation:
I know the Kutchicetus had a large tail and the Saber-toothed cat didn't becuase of anatomy and reasoning (the Kutchicetus dwells in water).
I know the Kutchicetus had thick blubber and the Saber-toothed cat didn't because of anatomy and reasoning (the Kutchicetus dwells in water).
I know the Saber-toothed cat lived in social groups and the Kutchicetus didn't because the Saber-toothed cat is related to lions (lions have social groups).
I know the Saber-toothed cat weighed twice as much as the lion because of research.
I know they both have proportionally small hind legs because of anatomy. (Images)

In photosynthesis and respiration, energy is converted from one form to another. Light is a form of radiant energy. Glucose and ATP molecules store chemical energy.
Q1: During photosynthesis, what role is played by the radiant energy of the sun? Explain your answer( in 1 or 2 sentences).
Q2: In photosynthesis, what form of energy is sunlight converted to, and how is this energy stored?
Q3: Does cellular respiration result in a net input of energy or a net output of energy? Explain( in 1 or 2 sentences).
Q4: How is the energy produced by respiration stored?
Answer::
Q1: During photosynthesis, the radiant energy of the sun is used to convert carbon dioxide and water into glucose and oxygen. This process is powered by the energy from the sun, which is absorbed by pigments in the chloroplasts of plant cells and used to drive the chemical reactions that produce glucose and oxygen.
Q2: In photosynthesis, the energy from sunlight is converted into chemical energy, which is stored in glucose and oxygen molecules. This process occurs in the chloroplasts of plant cells, where pigments absorb the energy from sunlight and use it to drive the chemical reactions that produce glucose and oxygen.
Q3: Cellular respiration results in a net output of energy. This process occurs in the mitochondria of cells, where glucose and other organic molecules are broken down to release the energy stored in their chemical bonds. The energy released during respiration is used to produce ATP, a molecule that stores chemical energy.
Q4: The energy produced by respiration is stored in the chemical bonds of ATP molecules. These molecules can be used to power various cellular processes, such as muscle contraction, synthesis of biomolecules, and transport of ions and molecules across cell membranes. When ATP is used to power these processes, the chemical energy stored in its bonds is released and converted into other forms of energy, such as mechanical energy or thermal energy.
Answer:
Q1: the sun provides the light energy that is converted into Glucose.
Q2: The light energy produced in Sunlight is stored and glucose to be later used as ATP
Q3: Cellular Respiration results in a net output of energy because Energy is RELEASED in the form of ATP in the process
Q4: the energy produced by respiration is stored as ATP to be used later.
Think about the sport you have chosen and the skills and movements involved. For example, the sport may require increased strength. Or it may require good balance or hand-eye coordination. What body systems are most directly involved in the skills needed for your chosen sport?
Please answer in at least 8 sentences and no scams
Answer:Improving your overall fitness can help you no matter what sport or other form of exercise you engage in. But where performance is concerned, the greatest improvements arise from training that develops skills specifically related to your activity of choice.
For instance, you need cardiovascular endurance and flexibility to play tennis. But to become good at tennis, you have to work on skill-related fitness components like agility, power, speed, and hand-eye coordination. It's this focus on activity-related skills that differentiate two distinct areas of fitness development.
Explanation:
Answer:
Regardless of what sport or activity you participate in, improving your general fitness can benefit you. However, when it comes to performance, the best results come from training that focuses on developing abilities relevant to your chosen activity.

vacation.
They will select different types of seeds, such as beans, peas, or sunflower seeds.
Encourage students to set up a germination experiment by placing the seeds in
different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to
pot the same seed in more than one pots.
They should observe and document the changes that occur over time, including the
emergence of roots and shoots.
Answer:
Okay...In this case I suggest you use corn seed or beans seed
Explanation:
It should take about 6 weeks to see the Germination, until then continue watering it and giving it sunlight
The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.
