Summarize symbiosis.
Answer:
Symbiosis is a close relationship between two species in which at least one species benefits. Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected.

parasitic plant and insecticide plant defination
parasitic plant = A parasitic plant is one that survives at the expense of another, often living and growing on and over the host plant, while siphoning off the other plant’s nutrients and water, and sometimes blocking access to sunlight.
insecticide plant = Insecticide, any toxic substance that is used to kill insects. Such substances are used primarily to control pests that infest cultivated plants or to eliminate disease-carrying insects in specific areas. insecticide application. A farmer sprays insectides in a rice paddy in Japan.

What process can change all three rock types in a new metamorphic rock?
Answer:
The three main rock types are igneous, metamorphic, and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

When there is no pattern to a
population's growth, it is known as
A. irregular
B. stable
C. irruptive
D. cyclical
When there is no pattern to a population's growth, it is known as stable. The correct option is B.
What is population growth?The rise in the number of people on Earth is referred to as population growth. The majority of human history saw a relatively steady population size. Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialisation.
The predicted population expansion is due in part to factors like an increase in young, unmarried mothers, high fertility rates for specific ethnic groups, and a lack of access to contraception and sexual education.
When age-specific fertility and mortality rates are constant over a long period of time, there is a stable population growth.
Contrarily, an irregular population increase is one in which there is no structure and the population size behaves chaotically.
Thus, the correct option is B.

using a named examples explain the differences between a specific body defence mechanism and a non- specific body defence mechanism
Answer:
Specific body defence mechanism are resistance that are directed against only one specific invader while,
Non specific defence mechanism protects against any of an enormous range of possible dangers.
Explanation:
NON SPECIFIC DEFENCE MECHANISM are the first lines of general defence, they prevent entry and minimise further passage of microbes and other foreign material into the body. There are five main non specific defence mechanisms, these include:
--> defence at body surface
--> phagocytosis
--> natural antimicrobial substances
--> inflammatory response
--> immunological surveillance
Using PHAGOCYTOSIS as a named example of non specific defence mechanism. This involves phagocytes such as the macrophages and neutrophils which are able to trap any invading microbes either by engulfing them or by extending long pseudopodia towards them which grasp them and reel them in. These cells are NON SELECTIVE in their targets.
SPECIFIC BODY DEFENCE MECHANISM directs its actions against a specific invader. In addition immunological memory develops which confers long term immunity to specific infections. The immunity could be cell mediated or antibody mediated immunity.
Using CELL MEDIATED IMMUNITY as an example, Cytotoxic T-cells directly inactivate any cells carrying antigens. This means they are SELECTIVE in their targets. They attach themselves to the target cell and release powerful toxins, which are very effective because the two cells are so close together. This leads to destruction of abnormal body cells such as infected cells and cancer cells.
True or false: according to natural selection, all organisms will have an equal chance of survival no matter what their traits are

Tadpoles must undergo a major metamorphosis to become frogs. This change includes reabsorption of the tail, growth of limbs, calcification of the skeleton, increase in rhodopsin in the eye, development of lungs, change in hemoglobin structure, and reformation of the gut from the long gut of an herbivore to the short gut of a carnivore. Amazingly, all of these changes are induced by triiodothyronine. What is the most likely explanation for such a wide array of effects of triiodothyronine
Answer:
The most likely explanation is that different body parts have different tissues which in turn have different thyroxine receptors. This leads to different signal transduction pathways.
Explanation:
The triiodothyronine absorption through different tissues lead to different signal transduction pathways.

Tendrá la intensidad de la luz un efecto en la velocidad de la fotosíntesis, cuando los períodos de exposición están limitados a la duración normal de la luz para una planta
Answer:
ver explicacion
Explanation:
La fotosíntesis es el proceso mediante el cual las plantas verdes fabrican su propio alimento en presencia de luz solar, clorofila, dióxido de carbono y agua.
La intensidad de la luz afecta la tasa de fotosíntesis, cuanto mayor es la intensidad de la luz, mayor es la tasa de fotosíntesis y viceversa. Cuando hay una mayor intensidad de luz, hay más luz disponible para impulsar las reacciones de la fotosíntesis.

In the human body, organ-systems interact with each other to maintain homeostasis. Using the diagram below, explain how this system interacts with another in the body to maintain homeostasis?
Answer:
D
Explanation:
Im pretty sure tell me if im right
Homeostasis is a regulating process of the body in response to external environments, digestive system provides glucose for cellular respiration.
How do organ systems interact to maintain homeostasis?Organ systems in our body are regulated with each other and these interactions maintain homeostasis.
The respiratory system interacts with the circulatory system for gaseous exchange and the excretory system depends on the circulatory system for blood filtration, and the nervous system regulates the system through the brain.
Homeostasis is necessary because the external environment can change anytime, and the digestive system maintains food conditions according to the body's needs.
Therefore digestive system maintains homeostasis by providing glucose for cellular respiration.

The four main forces that drive evolution are mutation, natural selection, genetic drift, and gene flow. All of these forces can cause a change in what?
Answer:
Allele frequencies
Explanation:
The only component that is transmitted from generation to generation is the genetic material (genes), the fact that an individual leaves more descendants implies that their genetic variants (alleles) will be more represented in the next generation. The frequencies of the different alleles will change from one generation to another, and this change will be irreversible when the set of genes in the population is considered, since it is highly unlikely that a previous configuration will be returned in all gene variants. Hence, from a population point of view, evolution is ultimately a cumulative and irreversible change in the proportions of different gene variants in populations. The agents that change the allele (or gene) frequencies of populations, that is, factors of evolution, are mutation, genetic drift, migration, and natural selection. Mutation is a factor that increases genetic diversity. Natural selection is the process by which the gene frequencies involved with certain traits vary from generation to generation, since some variants of the trait have a greater capacity than others to survive and produce offspring. The mutation rate of a gene or DNA sequence is the frequency at which new mutations occur in that gene or sequence in each generation. In each generation there is a gene raffle during the transmission of gametes from parents to children which is known as genetic drift. In the absence of gene flow, gene drift will also lead to local differences in allele frequencies.
