Answers
Answer:
The population of peppered moths thrived, because they camouflaged with the bark of the trees, thereby they were not easily seen by predators. Black moths were easily seen by predators and they were eaten as a result. Because the black moths did not survive, they were unable to reproduce offspring with those traits. However, peppered moths were able to reproduce offspring that were also peppered. During the industrial revolution, the colour of the bark darkened. This meant the peppered moths were easily seen by predators, so they were eaten. Black moths camouflaged with the bark, so now they weren't easily seen by predators. Now that the black moths survived, they could reproduce more black moths. But peppered moths weren't able to reproduce more peppered moths because most didn't survive. This is an example of how an abiotic factor, such as bark can affect a population of a species. Because the bark influenced the survival of the moths, some moths with the desirable traits survived, and others with the undesirable traits died.

A student keeps an onion bulb in a jar filled with water and observes that the roots continue to grow in length. The student cuts a root tip and observes it under a microscope. The image shows the observations. Which option supports the reason for an increase in the root’s length?The root cells undergo meiosis to expand and increase in length.
The root cells undergo mitosis to combine together to make the root grow.
The root cells undergo mitosis to form new identical cells.
The root cells undergo meiosis to form different types of cells.
Answers
Answer:
The root cells undergo mitosis to form new identical cells.
Explanation:
Mitosis is the process of cell division, where a cell divides into two equal cells with the same number of chromosomes. These new cells are used to promote the growth of a biological structure, promoting an elongation, a replacement, a concert, or an increase in volume. This can be seen in the case of the growth of the tip of the onion root, where the cells underwent mitosis, forming equal cells, to promote the growth of a new tip.
Oxygen gas production will happen within me
Answers
Answer:
Almost all the oxygen you breathe comes from green plants. They produce oxygen during a process called photosynthesis. During photosynthesis green plants manufacture the sugar molecules fructose and glucose. Green plants use energy from sunlight to build sugar molecules from carbon dioxide and water.
Plant cells contain organelles called chloroplasts that are essential for photosynthesis. Within chloroplasts, oxygen gas production will take place. So, the answer is chloroplast.
Plants use sunlight, water, and carbon dioxide to produce oxygen and sugar-based energy through a process known as photosynthesis. The process of photosynthesis results in the emission of oxygen gas.
Photosynthesis and release of oxygen processes occur within chloroplasts that generate energy that support plant growth and crop yield.
Although mitochondria are organelles that can be found in plant cells, they do not produce oxygen. Cellular respiration is carried out by mitochondria. Although cellular respiration consumes oxygen gas, it does not create oxygen gas.
Therefore, chloroplasts is the answer to the question "Oxygen gas production will happen within."

b. In a non-flowering plant, the embryo is in spores found in the stem, and in a flowering plant, the embryo is in seeds found in the flower.
c. In a non-flowering plant, the embryo is in seeds in the leaves, and in a flowering plant, the embryo is in seeds found in the spores.
d. In a flowering plant, the embryo is in spores found in the flower, and in a non-flowering plant, the embryo is in seeds found in the spores.
Answer:
The correct answer is - option a. In a flowering plant, the embryo is in seeds found in the flower, and in non-flowering plants, the embryo is in seeds found in the cone.
Explanation:
Non-flowering plants especially gymnosperms begin their life cycles from the embryo found inside the seeds like the flowering plants however, in gymnosperms these are found in the cone.
In the flowering plants, the embryo is present in the seeds present in the flower that develop into fruits too. Angiosperms are the flowering plants that produce seeds.
Thus, the statement best describes where the embryo can be found in flowering and non-flowering plants.

En los seres vivos acuaticos el oxigeno es tomado del __________ y penetra a la celula por el fenomeno de ___________
Answers
Answer:
En los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.
Explanation:
La respiración es el proceso mediante el cual los seres vivos obtienen oxígeno. Es decir, la respiración implica el reemplazo del dióxido de carbono en los pulmones por oxígeno del aire, y puede ser pulmonar, branquial, traqueal o cutánea.
La respiración branquial es un tipo de respiración propia de la mayoría de los animales acuáticos y se lleva a cabo en las branquias, unas estructuras con forma de láminas que contienen vasos sanguíneos. Los animales acuáticos dispone de estos órganos que permiten absorber el oxígeno que se encuentra en el agua y eliminar el dióxido de carbono.
El agua que entra por la boca y circula por las branquias, donde el oxígeno es absorbido, pasa a la sangre y es transportado a todo el cuerpo donde se produce una respiración celular.
Es decir, en los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.
Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants
Answers
Answer:
Resistance plants increase in number whereas non-resistant plants decreases.
Explanation:
The environment of rain forest is suitable for the fungal growth because of the presence of humidity in the environment and we know that fungi needs moist places for its growth. These fungus attached on the leaves and takes nutrients from that plant that leads to the stunted growth and many cases death of the plant occurs. Some plants have no effect of this fungus due to the presence of resistance in them so if the fungus spreads in the whole forest so the plants which are prone to these fungal infections eliminated from that environment and resistant plants are increase in number.
Answer:
Part B
Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants.

Think about the meaning of these words fruit seed germinate cotyledons, embryo ,plumule ,dormancy,root hairs. Write a sentence containing each of these words
Answers
Answer:
When a seed, taken from a fruit, is planted and watered under the correct temperature, it breaks dormancy, and the embryo germinates; first, the root grows covered by root hairs, then the cotyledons appear, and finally, the plumule elongates to reach the light.
Explanation:
Fruit: It forms by the mature ovary of the flowers. This structure contains and protects the seeds in its interior. Its principal function is to transport seeds to a distant area away from the parental plant and let the new plant emerge under the correct environmental conditions. The fruit develops different strategies to accomplish its function. Seed: Refers to the fecundated and mature ovule. This structure is the typical dissemination and dispersion unit of spermatophyte plants. Seeds are formed of three tissues. An embryo. A seminal tegument that covers and encloses the latent embryo. And the endosperm -a nutritious tissue-. Seeds develop and grow under the protection of the fruit body. Embryo: It is formed after fecundation. It composes of growing cotyledons, an epicotyl, and a hypocotyl. The tegument and endosperm of the seed protect the embryo from dehydration and denutrition. Once the seed is in the correct place, the embryo grows and emerges. Cotyledon: The two first leaves of the embryo. They have reserve nutritive tissues to help the embryo grow. It also performs photosynthesis. The embryo usually develops one or two cotyledons and one radicule or root hair. Plumule: First shoot of the young emerging plant. When the embryo is growing, it elongates to reach more sunlight. Root hairs: Extention of the roots´ cells that look like hairs and whose principal function is to absorb nutrients and water from the ground. They can be found in the maturation area of the root. Germination: Process of development and the emergence of the embryo. These are a series of steps that must occur in the seed from the moment the embryo begins to develop until a newly emerged plantule is formed. For germination to occur, there must be the appropriate environmental conditions. Dormancy: Period in which an alive seed can not germinate because there is a condition inside the seed that does not allow germination to occur yet. The seed is in dormancy, but it keeps viability.Which of the following describes positive feedback?
