A. Lamarck’s theory was discarded when new scientific information became available.
B. Darwin collected empirical evidence to support that organisms with favorable traits survived and reproduced.

2. Living cells come only from other living cells
3. Cells are the smallest unit of living things
The cell theory describes that all living things are composed of cells, living cells come only from the other living cells, and cells are the smallest unit of living things. Thus, the correct options are 1, 4, and 5.
What is the Cell theory?The cell theory was first proposed by the German scientists Theodor Schwann and Matthias Jakob Schleiden in the year 1838. The theory explains that all the living organisms such as plants and animals are made up of cells which is marked a great conceptual advance in the field of biology and resulted in renewed attention to the living processes which go on in the living cells.
The three major principles of cell theory are:
a. All living organisms are composed of one or more types of cells.
b. A cell is the basic structural and functional unit of the living organism.
c. All cells arise from the pre-existing cells.
Therefore, the correct options are 1, 4, and 5.

• home to many types of grazers
• experience all seasons of weather

• few trees due to little rainfall
1)
(Savannas)
(Both Types of

(Temperate

Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.
The strangler fig’s roots grow up and down the host tree, it latches onto. These roots eventually grow high enough to reach the sunlight in the cloud forest. Typically, after this happens the host tree eventually dies, leaving a hollowed-out center wrapped in large roots. What type of tropism is responsible for the hollowed-out tree? Explain your answer.
Answers
Answer:the relationship between host tree and strangler fig may be more mutually beneficial than previously thought, in a symbiosis where the host provides a structure to support the strangler fig's establishment in the well-lit canopy, and the strangler fig helps to support its host during storms
The aerial roots of strangler figs may attach to surrounding vegetation on the ground, stabilising the host plant and making it less likely to become uprooted. The leaves of the fig may also help shield from wind by closing up the forest canopy. Geotropism

In 4 or more complete sentences, describe the process of protein synthesis and explain how transcription and translation creates protein
Answers
Protein synthesis occurs in the cell and is divided into 2 stages, namely transcription and translation. The process of transcription occurs in the cell nucleus by copying the genetic code in DNA and forming mRNA strands which are duplicates of DNA.
The RNA strands that are formed will come out of the cell nucleus and then undergo a translation process that occurs in the cytoplasm. With the help of ribosomes, the amino acids will line up according to the sequence of the genetic code in the mRNA to form polypeptide chains that make up the protein structure.
What is protein synthesis?
Protein synthesis is the formation of proteins in the human body and occurs in the smallest units, namely cells. Protein synthesis is divided into 2 stages, in the following order:
1. Transcription
Transcription is the process of copying the genetic code or DNA that occurs in the cell nucleus or nucleus. The process of copying the genetic code is carried out by unbinding the DNA with the help of RNA polymerase, then forming a copy of the genetic code that is complementary to the sequence of hydrogen bases in the DNA. The process of transcription produces a strand of genetic code called mRNA or RNAd.2. Translation
Translation is the process of translating the genetic code contained in the mRNA and occurs in the cytoplasm. With the help of the ribosome, the mRNA will be translated and the amino acids will move towards the ribosome. Amino acids will form a sequence that is complementary to the mRNA so that a polypeptide strand that makes up the protein molecule is formed.Learn more about Protein synthesis at https://brainly.com/question/15404950
#SPJ1
1. Transcription:
Transcription is the first step in protein synthesis and takes place in the nucleus of eukaryotic cells or in the cytoplasm of prokaryotic cells. It involves the conversion of genetic information from DNA into a complementary RNA molecule. Here's how it works:
a. DNA unwinding: An enzyme called RNA polymerase binds to a specific region of the DNA molecule known as the promoter. The DNA molecule unwinds at this site.
b. Complementary RNA synthesis: RNA polymerase reads the DNA template strand and synthesizes a complementary RNA molecule, using adenine (A), cytosine (C), guanine (G), and uracil (U) as the RNA bases, instead of thymine (T). This newly formed RNA molecule is called messenger RNA (mRNA).
2. Translation:
Translation is the second step in protein synthesis and occurs in the cytoplasm, specifically at the ribosomes. It involves the conversion of the mRNA molecule into a functional protein. Here's how it works:
a. Initiation: The ribosome attaches to the mRNA molecule at a specific start codon (usually AUG), signaling the beginning of translation.
b. Elongation: Transfer RNA (tRNA) molecules bring amino acids to the ribosome, guided by the mRNA codons. These tRNA molecules have anticodons that complement the mRNA codons.
c. Peptide bond formation: As the ribosome moves along the mRNA molecule, it catalyzes the formation of peptide bonds between the amino acids carried by tRNA molecules. This forms a growing polypeptide chain.
d. Termination: Translation continues until a stop codon (UAA, UAG, or UGA) is encountered on the mRNA. At this point, a release factor binds to the ribosome, leading to the release of the completed polypeptide chain.
In summary, protein synthesis begins with transcription, where DNA is transcribed into mRNA. Then, during translation, the mRNA is decoded by ribosomes, and amino acids are linked together to form a polypeptide chain, which eventually folds into a functional protein. This intricate process ensures that the genetic information encoded in DNA is faithfully converted into the proteins that carry out essential functions within cells and organisms.
