The four ways by which land plants later evolved and became unique from their algal ancestors are:
Explanation:
The ancestors or close relatives of land plants are the green algae also called the charophytes. Land plants became unique from their algal ancestors due to evolutionary changes required for adaption with the environment.
Alteration in the successive generations of plant species, produces gametes and sporophytes through mitosis and meiosis. Embryonic growth at multicellular level, obtains nutrient from parent cells.Plants produces spores through sporangia and have multicellular gametangiaGrowth of plant occurs through apical meristems by differentiation of tissuesFour things that make plants unique to their algae ancestors are:
1. Plants have connective tissues that helps to transport nutrients and water throughout the plant. While in algae, each cell absorbs its own water. This makes algae non vascular.
2. Plants are multi-cellular that consists of chloroplasts, cellulose walls and also have the ability to make embryos while algae are generally single celled.
3. Algae majorly thrives in water that uses the minerals found in water to produce their own food but some can live on land and even on snow. However, Plants mostly grow on land because they use sunlight and CO2 to keep some of its most important biologic processes going on.
4. The mode of reproduction in plants is more complex compared to that of algae which is primitive.
why is atp important to biochemical reactions
Answer:
ATP stands for adenosine triphosphate. It is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities. ... ATP consists of one adenine molecule and three phosphate molecules.
Explanation:
Answer:
ATP is important as it transports the energy by its hydrolysis for different biochemical reactions required for cellular metabolic activities.
Explanation:
ATP is important in biochemical reactions due to following reasons:
ATP is able to storage and transportation of energy within cells. ATP helps in the synthesis of nucleic acids. The molecule acts in both of endergonic and exergonic processes of reactions and makes energetically unfavourable biochemical reactions possible .It is important in aerobic respiration, fermentation, cellular respiration, photophosphorylation and photosynthesis. The energy releasing ability of the ATP lies on its phosphate group; which when broken releases energy as an exothermic reaction.
The purpose of mitosis is to produce what
The purpose of meiosis is to produce what
ANSWER ASAP!!!!!!!!!!!!!
Mitosis produces two identical cells for growth and repair, while meiosis produces sex cells with genetic variation for sexual reproduction.
Explanation:The purpose of mitosis is to produce two identical daughter cells that have the same number of chromosomes as the parent cell. This process is crucial for growth, cell repair, and replacement in the body. An example of where mitosis occurs is in your skin cells, which are constantly being renewed and replaced.
On the other hand, the purpose of meiosis is to produce sex cells or gametes (sperm and egg cells) for sexual reproduction. These cells are not identical and they contain half the number of chromosomes compared to the parent cell. This genetic variation ensures the survival and evolution of species. For instance, in humans, meiosis in males produces sperm cells, and in females, it produces egg cells.

To carry out essential life processes the body must maintain?
Answer: homeostasis
Explanation:
Answer: homeostasis
Explanation:
Homeostasis depends on the body's ceaselessly carrying on many activities. Its major activities or functions are responding to changes in the body's environment, exchanging materials between the environment and cells, metabolizing foods, and integrating all of the body's diverse activities.
Define tissue with regards to anatomy *
A group of structurally and functionally related cells that come together to perform
common functions
O
A series of different cells in the same area
O
Multiple sheets of thin paper used to clean your nose
O
The smallest structural and functional unit of an organism
Answer:
A group of structurally and functionally related cells that come together to perform common functions
Explanation:
Each cell types has special features that enable it to perform a particular function efficiently. When a group of specialized, structurally and functionally related cells assemble together they form a tissue.
Tissue, in the context of anatomy, refers to a group of structurally and functionally related cells that come together to perform common functions. Tissues are made up of specialized cells that work together to carry out specific tasks in an organism. They are organized into higher levels of organization, such as organs and organ systems.
Explanation:Tissue, in the context of anatomy, refers to a group of structurally and functionally related cells that come together to perform common functions. These cells can be of the same type or different types, but they work together to perform specific tasks within an organism. For example, muscle tissue consists of cells that contract and generate force, allowing the body to move.
One important aspect of tissue is that it is made up of cells that are specialized for specific functions. This specialization allows tissues to perform their designated roles efficiently. Each type of tissue has characteristic cell types and structures that enable them to carry out their specific functions.
Tissues are organized into higher levels of organization, such as organs and organ systems, which work together to maintain the overall function of an organism. Understanding tissue structure and function is essential in the field of biology, as it helps explain how different parts of the body work together and how disruptions in tissue function can lead to health issues.

Fungi grow best in _______ and ________ areas.
Question 2 options:
cool; humid
warm; humid
warm; dry
cool; dry
Answer:
warm and humid
Explanation:
Fungi grow best in warm and humid areas. Only a few fungi are found in drier regions or in ecosystems with little to no organic matter, and soil rich in organic matter is a good habitat for many species.
What is the suitable temperature for fungus growth?Some fungi survive their whole life cycle on or inside their hosts, whether they be plants, animals, or both.
Warm temperatures are ideal for fungi growth. Some fungal species do grow better in warm temperatures (70–90°F), however, some also perform well at extremely high temperatures (130–150°F) and extremely low temperatures (below 32°F) (below freezing).
Mycelium is a network made up of many connected hyphae, which are the thread-like structure of fungi. Because different fungi vary in their complexity.
Therefore, fungi grow best in warm and humid areas option B is correct.

Researchers inserted a gene for bioluminescence into a variety of organisms, such as mosquito larvae. What is
this technology called?
A) gel electrophoresis
B) polymerase chain reactions
C) DNA sequencing
D) genetic engineering
Answer;
D generic engineering.
Explanation: Genetic engineering is the process of altering the genetic characteristics of species by substituting another species gene into them using biotechnology. It is the type of technology using to change the genetic make-up of cells.
It Is a genetic modification or manipulation to to transfer a gene of bioluminescence into that of mosquito lavae.
Final answer:
The technology used to insert a gene for bioluminescence into organisms is called genetic engineering, involving isolating the desired gene (like GFP), using restriction endonucleases to cut DNA, and creating a GMO that expresses the new trait. d)
Explanation:
The technology used when researchers insert a gene for bioluminescence into organisms is called genetic engineering. This process involves several steps, starting with isolating the DNA of interest, which in the case of getting E. coli cells to glow, would be the green fluorescent protein (GFP) that originates from jellyfish. Next, both the target DNA and the cloning vector DNA are cut using enzymes known as restriction endonucleases to create 'sticky ends' that facilitate the joining of the GFP gene into the vector DNA. The combination is then introduced into the organism, creating a transgenic or genetically modified organism (GMO) that can express the new trait, in this case, bioluminescence.
