Answer:
Ideas aimed at explaining how organisms change, or evolve, over time date back to Anaximander of Miletus, a Greek philosopher who lived in the 500s B.C.E. Noting that human babies are born helpless, Anaximander speculated that humans must have descended from some other type of creature whose young could survive without any help. He concluded that those ancestors must be fish, since fish hatch from eggs and immediately begin living with no help from their parents. From this reasoning, he proposed that all life began in the sea.

Explanation:
different seeds need different cultivation. justify in 200 words.
for 18 points
Answer:
Cultivation is the process of growing crops. we need different seeds to cultivate different types of food. Similarly, different seeds need different cultivation. For eg: we grow potatoes in well-drained loam soil. But we grow rice in muddy soil. Every seed has a different way to produce food. They need different temperate or climates, different types of soil, to grow them. They have their own time or season to grow and produce food. If we try to grow plants or vegetables in the wrong season or the wrong process, then we can't get a good result. For eg: If we try to grow rice in drained soil then it will not give us a good result or if we try to grow potatoes in muddy soil we cant get our good result.
So, we can say that different seeds need different cultivation.

A small size is advantageous for marine organisms because it ________. increases the surface area to volume ratio that in turn reduces frictional resistance to sinking increases the ability to absorb nutrients increases the ability of wastes to diffuse out of the organism All of the above
Answer:
increases the ability of wastes to diffuse out of the organism
Explanation:
A small size of an organism is advantageous for marine organisms because it increases the ability of wastes to diffuse out of the body of organism. Small size of an organism produces less amount of waste material and these organism does not need a very special and complex excretory system so simple diffusion of waste material occurs from the body in order to clean the body.

1. Scales are used to figure out the ratio of the distance in the map to the actual distance between locations.
A. what is the name of two different types of scales found on maps?
B. how does each scale work?
Answer:
Bar and lexical.
Explanation:
Bar and lexical are the name of two different types of scales that are found on maps. Bar scales are used more frequently in the maps because they represent or show the distance ratio visually instead of in words, while on the other hand, lexical scales may be expressed in words, as a ratio, or as a fraction. Examples are 1:10,000 or 1/10,000. Using map scales is very important in the real world if you want to find out the distance you are traveling.

In the plasma membrane, the phospholipid heads Group of answer choices are isotonic and do not respond to water. are hydrophobic and face inward, shielded from water. are hydrophilic and face inward, shielded from water. are hydrophilic and face outward toward the aqueous solution on both sides of the membrane. are hydrophobic and face outward toward the aqueous solution on both sides of the membrane.
Answer:
hydrophilic and face outward toward the aqueous solution on both sides of the membrane
Explanation:
The cell membrane is mainly composed of phospholipids, which are arranged in a lipid bilayer. In general, phospholipids consist of a glycerol unit, a phosphate group, and two fatty acids. In a lipid bilayer, hydrophilic (polar) phosphate heads are always oriented outwards and interact with surrounding water molecules; whereas hydrophobic fatty acid tails are oriented towards the center of the lipid bilayer away from water. It is for that reason that phospholipids are considered to be amphipathic molecules, where fatty acids confer hydrophobic properties and polar phosphate groups confer hydrophilic properties.

Determine if the statement is true or false, and why. “Most features are caused by a mixture of inheritance and environmental factors.”
A. False, it should read “Most features are caused by inheritance.”
B. True
C. False, it should read “Most features are caused by environmental factors.”
D. False, it should read “All features are caused by a mixture of inheritance and environmental factors.”
The statement is False, it should read, Most features are caused by inheritance of a character. Thus option A is correct.
What is inherited trait ?Inheritance is defined as the transfer of genetic information from parents to their offspring.
The transferred characters or traits include eye color, hair color, and blood type.
Trait can be defined as the genetic character which can be transmitted by the parent to its offspring during fertilization.
The trait which is expressed phenotypically is called as dominant trait while the other trait which is not expressed called as recessive trait.
These variations are observed in the species due to survival benefits or genetic drift.
Acquired traits are acquired by an individual in his lifetime which is due to their own activities or external influence.
Like inherited traits, acquired traits are unable tp pass to the next generation like ability to dance, cook.
Thus option A is correct.

Give a positive and a negative impact of an environmental law or regulation.
Answer:
negative impact
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
positive impact
Environmental regulations have greatly improved air and water quality, especially in areas that were dirtiest before regulation. Reducing airborne particulates is especially beneficial, saving thousands of lives and preventing millions of illnesses each year.
A technique that can be used to separate proteins based primarily on the presence of non-polar residues on their surface is called A) ion-exchange chromatography. B) gel filtration chromatography. C) affinity chromatography. D) gel electrophoresis. E) hydrophobic interaction chromatography.
Answer:
E) hydrophobic interaction chromatography.
Explanation:
Hydrophobic interaction chromatography (HIC) is a methodology used to separate protein molecules depending on their hydrophobicity. HIC enables the separation and purification of proteins by using a reversible interaction between the target protein and the hydrophobic ligand of a HIC resin such as, for example, methacrylate-based beads. This interaction is influenced by the running buffer (high salt concentrations favor hydrophobic interactions). HIC enables the separation of proteins under low denaturation conditions, thereby preserving their biological functions.

Give a reason why lack of roughage in diet often lead to constipation?
Answer:
Roughages increase fecal volume and promote peristalsis
Explanation:
Constipation refers to the condition in which bowel evacuations occur infrequently, leading to health problems. Some of the most common causes of constipation include 1-insufficient intake of dietary fibers or roughages, 2-poor hydration, 3-lack of physical exercise, 4-abuse of laxatives, etc. Dietary fibers are divided into two classes based on their water solubility: soluble and insoluble. These fibers represent the part of plant foods that the body can't digest, which absorbs and retains water (soluble fibers) as foods pass through the bowel and create bulk (insoluble fibers), thereby leading to regular bowel habits.
