how do scientists use models to determine the scale properties of objects in our solar system
Answer:
They use a ruler to draw a line for diameter
Explanation:
Answer:
A scale model uses the same measurement ratios as the real object does. The first model will compare the distance the planets are from the sun in astronomical units, the other model will compare the size of the planets using diameters in kilometers.

A. flower can produce many seeds at the same time.
b. The same plant can produce many flowers.
C. Flowers can be pollinated without the involvement of animals.
d. Flowers produce seeds that are encased in protective fruits
Answer:
Its not a flower can produce many seeds at the same time
Explanation:
D. Flowers produce seeds that are encased in protective fruits is a property of the flowers of angiosperms that is not shared by the reproductive structures of gymnosperms.
What are gymnosperms?Gymnosperms are a group of seed-bearing plants that produce seeds that are not enclosed within a fruit. They are found in a wide range of habitats, from deserts to mountainous regions, and include many well-known species such as pine, spruce, and fir trees.
Gymnosperms are an ancient group of plants that have been around for over 300 million years, and they play an important role in many ecosystems by providing habitat, food, and other resources for wildlife and humans.

Which direction does Xylem flow? Phloem?
Answer:
The movement of Xylem is unidirectional and phloem is bidirectional
Explanation:
The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.
Phloem transport is bidirectional because sucrose gets accumulated in the phloem tissue and absorbs water creating a high turgor pressure. ... Hence the water flows from regions of high turgor pressure to low turgor pressure and the direction can be upwards or downwards from the leaves based on the gradient.

Answer:
There are 5 sacral vertebrae that are fused into one sacrum. There are seven cervical vertebrae, some of them containing a transverse foramen. There are twelve thoracic vertebrae, most of them with a long spinous process. The vertebral column is composed of thirty-three vertebrae distributed into 5 regions. There are three to 5 bones in the coccyx, with variability in the fusion. There are five lumbar vertebrae, which have large vertebral bodies.
Explanation:
The vertebral column has 33 vertebras and five sections. They are the cervical spine with seven vertebrae, the thoracic spine with twelve vertebrae, the lumbar spine with five vertebrae, the sacrum with five fused vertebrae, and lastly, the coccyx with three to five vertebrae. The vertebrae in each section have different characteristics. For example, the length of the spinous process changes becoming longer as we descend in the cervical and the thoracic spine, or the body of the vertebrae has different shapes in each section, or the presence of the transverse foramen in the cervical spine, which allow the passage of a nerve plexus, an artery, and a vein. Each section, with its characteristics, aligns to form the vertebrae column containing and protecting the spinal cord.

Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation of reptiles except for birds. The reptiles have a three-chambered heart that consists of two atria and one ventricle with an incomplete septum. There are two circuits: pulmonary and systemic. In the pulmonary circuit, the blood from the right ventricle is pumped in to lung capillaries and returned to the left atria. In the systemic circuit, the blood is pumped from the left ventricle to the systemic capillaries via the left systemic aorta and is then returned to the right atria. There is also one vessel going from the right ventricle to the aorta right before it branches to smaller arteries. This vessel carries mixed blood. All blood on the right side of the circuits is venous and all blood on the left side is arterial. Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart. The three-chambered heart is inferior to the four-chambered hearts of birds and mammals, limiting the evolutionary success of amphibians and nonbird reptiles. Pulmonary and systemic blood fully mixes in the ventricle of a three-chambered heart.
Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

What is the enzyme?Proteins called enzymes assist our bodies' chemical reactions move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial. Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.How do you classify enzymes?According to the sort of process they catalyze, enzymes are divided into six categories:
Oxidoreductases. Transferases.Hydrolases.Lyases.Ligases.Isomerases.What are the 7 enzymes?Depending on the type of reaction they catalyze, enzymes can be divided into seven different types. These groups include hydrolases, lyases, isomerases, ligases, translocases, oxidoreductases, transferases, and hydrolases.What is enzyme structure?Proteins called enzymes are made up of amino acids connected by one or more polypeptide chains. The fundamental structure of a polypeptide chain refers to this arrangement of amino acids. This in turn dictates the enzyme's three-dimensional structure, including the active site's shape.Learn more about enzyme here:
