Answer:
the type of food changes
Explanation:
Natural selection is the force by which populations adapt and change (or evolve), increasing the prevalence of advantageous phenotypic traits. According to the evolutionary theory proposed by Darwin, organisms that are better suited to the environment are selected through the mechanism of natural selection. In this case, birds with beaks better suited to the type of available food in the area will be more chances to survive and reproduce, perpetuating their genes in the next generation.

explain the types of parenchyma tissues with their function
Answer:
Parenchyma
Parenchyma is a tissue composed of polyhedral living cells having thin walls and is concerned with vegetative activities of the plant. The individual cells of the tissue are called parenchyma cells.
Types of parenchyma:
Assimilatory: parenchyma cells which take part in photosynthesis contain chloroplasts and form a tissue called Chlorenchyma. These cells have a single or many vacuoles.
Storage Parenchyma: Some parenchyma cells contain leucoplasts. Parenchyma cells may store reserve materials. Amides, proteins and sugars are found dissolved in cell sap, as in roots of sugar-beet. Starch, proteins and fats occur in cytoplasm in the form of small particles. Proteins, starch grains and oils are found in the endosperm and cotyledons of many plants. In succulent plants, parenchyma cells which store water are present. Such cells are large, thin-walled and have only a thin layer of cytoplasm.
Aerenchyma: The tissues with prominent intercellular spaces is called Aerenchyma, e.g., occurring in plants growing in waterlogged soils and aquatic environments.
Pseudo-parenchyma: These are thin walled and elastic and meristematic in nature.
Chromoplast Parenchyma: Chromoplast contain pigments and is common in petals of flowers, fruits etc.
Origin:
Parenchyma tissue of the primary plant body, i.e., parenchyma of the cortex and the pith, of mesophyll of leaves and of flower parts, differentiates from the ground meristem. The parenchyma associated with the primary and secondary xylem is formed from pro-cambium and the vascular cambium. Parenchyma also rise from the phellogen in the form of phelloderm.
Functions Of Parenchyma Tissues
In plant’s body or in its organs, the cell wall parenchyma appears as ground substance in which other tissues such as vascular tissues are embedded.
The apical meristems and the reproductive cells are parenchymatous. These are also involved in the phenomenon of wound healing and regeneration.
The parenchyma is also precursor of the other tissues. The parenchyma cells bring about the functions of photosynthesis, assimilation, respiration, storage, secretion, excretion, etc., as they have living protoplast.
The parenchyma cells associated with xylem and phloem are connected with transportation of food and water.
The intercellular larger portions of plants, such as pith, all or most, of the cortex of the root and shoot, the pericycle, the mesophyll of the leaf, and the fleshy parts of the root and shoot, the pericycle, the mesophyll of the leaf and the fleshy parts of the fruit consist of parenchyma cells. They are also present in xylem and phloem.

Use the drop-down menus to match each part of the scenario to the correct scientific practice.
Kiran records the height of each plant―those with a colored filter and those without.
Kiran explores the growth of a plant in natural light, then repeats the experiment with the same plant type but different colored filters.
Kiran turns in a written lab report to her science teacher.
Kiran wonders, “Will colored light affect the growth of a plant?”
Kiran writes in her notes that adding a colored filter over a plant affects its growth because the heights of the plants under the colored filters were less than the height of the plant with no filter.

What is the function of DNA Sequencers?
The Deoxy Ribo nucleic acid (DNA) is a molecule which contains the instructions needed for an organism to develop, live and reproduce.
What is DNA Sequencing?The laboratory technique which is used to determine the order of the four bases which make up the DNA molecule is defined as the DNA sequencing. The genetic information that is carried in a particular DNA segment is given by DNA Sequencing.
A scientific instrument used to perform DNA sequencing is called the DNA sequencer. The order of the bases (Adenine), (Guanine), (Cytosine) and (Thymine) is determined by DNA sequencer.

how do the four female hormones control the menstrual cycle
Answer: The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone.There are four major hormones (chemicals that stimulate or regulate the activity of cells or organs) involved in the menstrual cycle: follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone. hope this helps have a nice night❤️❤️❤️
Explanation:
The correct answer is A. It emphasizes that Japan had purposely deceived the United States
Explanation:
The excerpt presented belongs to toFranklin Roosevelt's speech in reference to the Pearl Harbor attack that took place in 1941 as the Japanese forces attacked one military based on Hawaii. In this speech Roosevelt states "the distance of Hawaii from Japan makes it obvious that the attack was deliberately planned" that shows from Roosevelt's perspective the attack was not spontaneous but has been planned which is emphasize with the use of "the distance of Hawaii from Japan" that show the attack followed a plan and especially the use of the word "deliberately" that means carefully considered or discussed before action, which shows the attack had been considered and planned before it occurred and therefore Japan attack on purpose to the U.S. Considering this, it can be concluded Answer:

1. Can all substrates fit in all enzymes? Why or Why not?
2. What happens to the substrate after it binds to the active site of an enzyme?
Pls help me this is for today!!
Answer:
1. Different enzymes have different substrates. Enzymes have different shaped active sites, that only a specific substrate can fit in the active site. In order for the enzyme to be broken down
2. After the substrate binds to the active site of an enzyme, the enzyme is broken down into smaller molecules. The substrate is not used up in this process, and is free to move around to other enzymes. The substrate then binds with the active site of the next enzyme, causing it to break down

Why is a thin rubber sheet used in the breathing mechanism instead of a thick rubber sheet
A thin rubber sheet is used because it stretches more easily compared to a thick rubber sheet and it makes pulling and pushing easier.
A thin rubber sheet is used because it stretches more easily compared to a thick rubber sheet and it makes pulling and pushing easier.
What are the functions of thin rubber sheet?Flooring and roofing applications are the most popular uses of rubber sheets in the industry. Rubber provides good resistance to substances like oil and petroleum.It has excellent tensile, elongation, tear resistance and resilience.
Rubber Products manufactures different kinds of rubber sheets which include natural rubber sheets, neoprene sheets, EPDM rubber sheets, silicone rubber sheets, nitrile rubber sheets as well as fabric enforced ones.
Rubber-sheeting is necessary because the imagery and the vector data will rarely match up correctly due to various reasons, such as the angle at which the image was taken.

In wild bees 75% of the population express wider shorter wings in domesticated bees 67% have longer narrower wings. Which trait is the dominant? Which trait is recessive?
Answer:
For wild bees, for domesticated bees, wider shorter wing is dominant whereas longer narrower wing is dominant trait.
Explanation:
In the wild bees, wider shorter wings trait dominant and longer narrower wings are recessive because most of the population shows wider shorter wings in the bees while on the other hand, in domesticated bees, longer narrower wings is dominant trait whereas wider shorter wings is recessive. The reason is that longer narrower wings are present in most of the population of domesticated bees.
